The United States Naval Research Laboratory (NRL) is the corporate research laboratory for the United States Navy and the United States Marine Corps. It conducts basic scientific research, applied research, technological development and prototyping. The laboratory's specialties include plasma physics, space physics, materials science, and tactical electronic warfare. NRL is one of the first US Government scientific R&D laboratories, having opened in 1923 at the instigation of Thomas Edison, and is currently under the Office of Naval Research. billion per year.NRL's research expenditures are approximately $1
The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. It is the largest and most capable navy in the world and it has been estimated that in terms of tonnage of its active battle fleet alone, it is larger than the next 13 navies combined, which includes 11 U.S. allies or partner nations. with the highest combined battle fleet tonnage and the world's largest aircraft carrier fleet, with eleven in service, and two new carriers under construction. With 319,421 personnel on active duty and 99,616 in the Ready Reserve, the Navy is the third largest of the service branches. It has 282 deployable combat vessels and more than 3,700 operational aircraft as of March 2018, making it the second-largest air force in the world, after the United States Air Force.
The United States Marine Corps (USMC), also referred to as the United States Marines or U.S. Marines, is a branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations with the United States Navy as well as the Army and Air Force. The U.S. Marine Corps is one of the four armed service branches in the U.S. Department of Defense (DoD) and one of the seven uniformed services of the United States.
Space physics is the study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System. As such, it encompasses a far-ranging number of topics, such as heliophysics which includes the solar physics of the Sun: the solar wind, planetary magnetospheres and ionospheres, auroras, cosmic rays, and synchrotron radiation. Space physics is a fundamental part of the study of space weather and has important implications in not only to understanding the universe, but also for practical everyday life, including the operations of communications and weather satellites.
The Naval Research Laboratory conducts a variety of basic and scientific research and technological development of importance to the Navy. It has a history of scientific breakthroughs and technological achievements dating back to its foundation in 1923.In some instances the laboratory's contributions to military technology have been declassified decades after those technologies have become widely adopted. In 2011, NRL researchers published 1,398 unclassified scientific & technical articles, book chapters and conference proceedings. In 2008, the NRL was ranked No. 3 among all U.S. institutions holding nanotechnology-related patents, behind IBM and the University of California.
Nanotechnology ("nanotech") is manipulation of matter on an atomic, molecular, and supramolecular scale. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter which occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size. Because of the variety of potential applications, governments have invested billions of dollars in nanotechnology research. Through 2012, the USA has invested $3.7 billion using its National Nanotechnology Initiative, the European Union has invested $1.2 billion, and Japan has invested $750 million.
International Business Machines Corporation (IBM) is an American multinational information technology company headquartered in Armonk, New York, with operations in over 170 countries. The company began in 1911, founded in Endicott, New York, as the Computing-Tabulating-Recording Company (CTR) and was renamed "International Business Machines" in 1924.
The University of California (UC) is a public university system in the U.S. state of California. Under the California Master Plan for Higher Education, the University of California is a part of the state's three-system public higher education plan, which also includes the California State University system and the California Community Colleges System.
Current areas of research at NRL include:
In 2014, the NRL was researching: armor for munitions in transport, high-powered lasers, remote explosives detection, spintronics, the dynamics of explosive gas mixtures, electromagnetic Railgun technology, detection of hidden nuclear materials, graphene devices, high-power extremely high frequency (35–220 GHz) amplifiers, acoustic lensing, information-rich orbital coastline mapping, arctic weather forecasting, global aerosol analysis & prediction, high-density plasmas, Millisecond pulsars, broadband laser data links, virtual mission operation centers, battery technology, photonic crystals, carbon nanotube electronics, electronic sensors, mechanical nano-resonators, solid-state chemical sensors, organic opto-electronics, neural-electronic interfaces and self-assembling nanostructures.
A railgun is a device that uses electromagnetic force to launch high velocity projectiles, by means of a sliding armature that is accelerated along a pair of conductive rails. It is typically constructed as a weapon, and the projectile normally does not contain explosives, instead relying on the projectile's high speed to inflict damage. The railgun uses a pair of parallel conductors - 'rails' - along which a sliding armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature and then back along the other rail. It is based on principles similar to those of the homopolar motor.
Graphene is an allotrope (form) of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It is a semimetal with small overlap between the valence and the conduction bands. It is the basic structural element of many other allotropes of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes.
Extremely high frequency (EHF) is the International Telecommunication Union (ITU) designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). It lies between the super high frequency band, and the far infrared band, the lower part of which is also referred to as the terahertz gap. Radio waves in this band have wavelengths from ten to one millimetre, so it is also called the millimetre band and radiation in this band is called millimetre waves, sometimes abbreviated MMW or mmW. Millimetre-length electromagnetic waves were first investigated in the 1890s by Indian scientist Jagadish Chandra Bose.
The laboratory includes a range of R&D facilities. 2014 additions included the NRL Nanoscience Institute's 5,000 sq ft (460 m2) Class 100 nanofabrication cleanroom; quiet and ultra-quiet measurement labs; and the Laboratory for Autonomous Systems Research (LASR).
The Naval Research Laboratory has a long history of spacecraft development. This includes the second, fifth and seventh American satellites in Earth orbit, the first solar-powered satellite, the first surveillance satellite, the first meteorological satellite and the first GPS satellite. Project Vanguard, the first American satellite program, tasked NRL with the design, construction and launch of an artificial satellite, which was accomplished in 1958. As of 2013 [update] , Vanguard I and its upper launch stage are still in orbit, making them the longest-lived man-made satellites. Vanguard II was the first satellite to observe the Earth's cloud cover and therefore the first meteorological satellite. NRL's Galactic Radiation and Background I (GRAB I) was the first U.S. intelligence satellite, mapping out Soviet radar networks from space. The Global Positioning System (GPS) was invented at NRL and tested by NRL's Timation series of satellites. The first operational GPS satellite, Timation IV (NTS-II) was designed and constructed at NRL.
Project Vanguard was a program managed by the United States Naval Research Laboratory (NRL), which intended to launch the first artificial satellite into Earth orbit using a Vanguard rocket as the launch vehicle from Cape Canaveral Missile Annex, Florida.
Galactic Radiation and Background (GRAB) was the covername for a series of five Project Dyno ELINT intelligence satellites, the first surveillance satellites operated by the U.S. Naval Research Laboratory (NRL) shortly after the Cold War U-2 incident of 1960. Though only two of the five satellites made it into orbit, they returned a wealth of information on Soviet air defense radar capabilities.
The Soviet Union, officially the Union of Soviet Socialist Republics (USSR), was a socialist state in Eurasia that existed from 30 December 1922 to 26 December 1991. Nominally a union of multiple national Soviet republics, its government and economy were highly centralized. The country was a one-party state, governed by the Communist Party with Moscow as its capital in its largest republic, the Russian Soviet Federative Socialist Republic. Other major urban centres were Leningrad, Kiev, Minsk, Alma-Ata, and Novosibirsk. It spanned over 10,000 kilometres east to west across 11 time zones, and over 7,200 kilometres north to south. It had five climate zones: tundra, taiga, steppes, desert and mountains.
NRL pioneered the study of the sun Ultraviolet and X-Ray spectrum and continues to contribute to the field with satellites like Coriolis (satellite) launched in 2003. NRL is also responsible for the Tactical Satellite Program with spacecraft launched in 2006, 2009 and 2011.
The Coriolis satellite is a Naval Research Laboratory (NRL) and Air Force Research Laboratory (AFRL) Earth and space observation satellite launched from Vandenberg Air Force Base, on 2003-01-06 at 14:19 GMT.
During the second half of 2002, the Naval Research Laboratory studied the tactical application of space assets. Relatively new technologies and processes in the areas of microsatellites, affordable and quick-response launch vehicles, and the classified SIPRNET made tactical use of space assets possible in the relatively near term. The DOD’s Office of Force Transformation (OFT) agreed with the core findings of the study and decided to start an Operationally Responsive Space Initiative consisting of a series of experiments. TacSat-1 is the first experiment in this OFT initiative. The TacSat-1 experiment received go-ahead on May 7, 2003.
The NRL designed the first satellite tracking system, Minitrack, which became the prototype for future satellite tracking networks. Prior to the success of surveillance satellites, the iconic parabolic antenna atop NRL's main headquarters in Washington, D.C. was part of Communication Moon Relay, a project that utilized signals bounced off the Moon both for long-distance communications research and surveillance of internal Soviet transmissions during the Cold War.
NRL's spacecraft development program continues today with the TacSat-4 experimental tactical reconnaissance and communication satellite. In addition to spacecraft design, NRL designs and operates spaceborne research instruments and experiments, such as the Strontium Iodide Radiation Instrumentation (SIRI) and RAM Angle and Magnetic field sensor (RAMS) aboard STPSat-5, the Wide-field imager for solar probe (WISP) aboard the Parker Solar Probe, and the Large Angle and Spectrometric Coronagraph Experiment (LASCO) aboard the Solar and Heliospheric Observatory (SOHO). NASA's Fermi Gamma-ray Space Telescope (FGST) [formerly called Gamma-ray Large Area Space Telescope (GLAST)] was tested at NRL spacecraft testing facilities. NRL scientists have most recently contributed leading research to the study of novas and gamma ray bursts.
The Marine Meteorology Division (Naval Research Lab–Monterey, NRL–MRY), located in Monterey, California, contributes to weather forecasting in the United States and around the world by publishing imagery from 18 weather satellites. Satellite images of severe weather (e.g. hurricanes and cyclones) that are used for advanced warning often originate from NRL–MRY, as seen in 2017 during hurricane Harvey.NRL is also involved in weather forecasting models such as the Hurricane Weather Research and Forecasting model released in 2007.
NRL has a long history of contributions to materials science, dating back to the use of Industrial radiography with gamma rays for the nondestructive inspection of metal casings and welds on Navy vessels beginning in the 1920s. Modern mechanical fracture mechanics were pioneered at NRL and were subsequently applied to solve fracture problems in Navy vessels, commercial aircraft and Polaris missiles. That knowledge is in widespread use today in applications ranging from design of nuclear reactors to aircraft, submarines and toxic material storage tanks.NRL developed the synthesis of high-purity GaAs crystals used in a myriad of modern high frequency transceivers including cellular phones, satellite communication systems, commercial and military radar systems including those aboard all US combat aircraft and ARM, Phoenix, AIM-9L and AMRAAM missiles. NRL's GaAs inventions were licensed by Rockwell, Westinghouse, Texas Instruments and Hughes Research. High-purity GaAs is also used for high-efficiency solar cells like those aboard NASA's Spirit and Opportunity rovers currently on Mars.
Fundamental aspects of stealth technology were developed at NRL, including the radar absorption mechanisms in ferrite-containing materials.Metal bearing surface treatments using Cr ion implantation researched at NRL nearly tripled the service life of Navy turbine engine parts and was adopted for Army helicopter parts as well. Fluorinated polyurethane coatings developed at NRL are used to line fuel storage tanks throughout the US Navy, reducing leakage and environmental and fuel contamination. The same polymer films are used in Los Angeles-class submarine radomes to repel water and enable radar operation soon after surfacing.
Scientists at NRL frequently contribute theoretical and experimental research on novel materials,particularly magnetic materials and nanomaterials and thermoplastic.
The first modern U.S. radar was invented and developed at NRL in Washington, DC in 1922. By 1939, NRL installed the first operational radar aboard the USS New York, in time for radar to contribute to naval victories of the Coral Sea, Midway and Guadalcanal. NRL then further developed over-the-horizon radar as well as radar data displays.NRL's Radar Division continues important research & development contributing to US Navy and US Department of Defense capabilities.
NRL's Tactical Electronic Warfare (TEW) Divisionis responsible for research and development in support of the Navy's tactical electronic warfare requirements and missions. These include electronic warfare support measures, electronic countermeasures, and supporting counter-countermeasures, as well as studies, analyses, and simulations for determining and improving the performance of Electronic Warfare systems. NRL TEW includes aerial, surface, and ground EW within its scope. NRL is responsible for the identification, friend or foe (IFF) system and a number of other advances.
The Information Technology Divisionhas a world-class information security R&D group, which is where the IETF's IP Security (IPsec) protocols were originally developed. The Encapsulating Security Payload (ESP) protocol developed at NRL is widely used for virtual private network (VPN) connections worldwide. The projects developed by the laboratory often become mainstream applications without public awareness of the developer; an example in computer science is onion routing, the core principle of the anonymizing Tor software.
Nuclear power research was initiated at NRL as early as 1939,six years before the first atomic bomb, for the purpose of powering submarines. Uranium enrichment methods sponsored by NRL over the course of World War II were adopted by the Manhattan Project and guided the design of Oak Ridge National Laboratory's Uranium enrichment plant. NRL is currently developing laser focusing techniques aimed at inertial confinement fusion technology.
The Static discharger seen on trailing edges of virtually all modern aircraft was originally developed by NRL scientists during World War II. After the war, the laboratory developed modern synthetic lubricantsinitially for use in the Navy's jet aircraft but they were subsequently adopted by the commercial jet industry.
In the late 1960s, NRL researched low-temperature physics, achieving for the first time a temperature within one millionth of a degree of absolute zero in 1967. In 1985 two scientists at the laboratory, Herbert A. Hauptman and Jerome Karle, won the Nobel Prize for devising direct methods employing X-ray diffraction analysis in the determination of crystal structures.Their methods form the basis for the computer packages used in pharmaceutical labs and research institutions worldwide for the analysis of more than 10,000 new substances each year.
NRL has most recently published research on quantum computing,quantum dots, plasma shockwaves, thermodynamics of liquids, modeling of oil spills and other topics.
NRL operates a small squadron of research aircraft termed Scientific Development Squadron ONE VXS-1. Its missions include, for example, Rampant Lion, which used sophisticated airborne instrumentation (gravimeters, magnetometers and hyperspectral cameras) to collect precise 3D topography of two-thirds of Aghanistan and locate natural resources (underground gas and mineral deposits, vegetation types, etc.) thereand in Iraq and Colombia.
The Division of Plasma Science conducts research and development into ionized matter. NRL currently holds the world record for most energetic rail gun projectile (33 MJ, 9.2 kWh) and fastest man-made projectile (334 million mph, 538 million km/h).
The laboratory is divided into four research directorates, one financial directorate, and one executive directorate. All the directorates are headquartered in Washington, D.C. Many directorates have other facilities elsewhere, primarily at either the Stennis Space Center in Bay St Louis, Mississippi or in Monterey, California.
Most NRL staff are civilians in the civil service, with a relatively small number of Navy enlisted personnel or officers. In addition, there are some support contractors that work on-site at NRL. As of 31 December 2015, across all NRL locations, NRL had 2540 civilian employees (i.e., not including civilian contractors).On the same date, there were 35 military officers on-board NRL and 58 enlisted on-board NRL, most of whom are with NRL's VXS-1 Scientific Flight Detachment, which is located at the Patuxent River ('Pax River') Naval Air Station (NAS) in southern Maryland.
NRL has special authority to use a Pay-Band pay system instead of using the traditional General Schedule (GS) pay system for its civilian employees.This gives NRL more ability to pay employees based on performance and merit, rather than time-in-grade or some other seniority metric. There are several different pay-band groups at NRL, each being for different categories of civilian employees. As of 31 December 2015, NRL had 1615 civilian scientists/engineers in the NP pay system, 103 civilian technicians in the NR pay system, 383 civilian administrative specialists/professionals in the NO pay system, and 238 civilian administrative support staff in the NC pay system.
NRL scientists & engineers typically are in the (NP) pay group in NRL's Pay Band system.The NP-II pay band is equivalent to GS-5 Step 1 through GS-10 Step 10. The NP-III pay band is equivalent to GS-11 Step 1 through GS-13 Step 10. NRL's Pay Band IV corresponds to the GS-14 Step 1 to GS-15 Step 10 pay grades, inclusive, while NRL's Pay Band V can pay above GS-15 Step 10 and corresponds to the Senior Technologist (ST) pay grade elsewhere in the civil service. A new graduate scientist or engineer with a Bachelor of Science degree typically is hired with a salary equivalent to a GS-7, while a new graduate scientist or engineer with a Master of Science degree typically at the equivalent of a GS-11.
According to the NRL Fact Book (2016), of NRL civilian full-time permanent employees, 870 had a doctorate, 417 had a master's, and 576 had a bachelor's as their highest degree.
The laboratory also hosts post-doctoral researchers and was voted #15 in the Best Places to Work PostDocs 2013 survey.
The four research directorates within NRL are:
The two support directorates are:
In April 2001, in a departure from traditional working relationships between NRL scientists, the Institute for Nanoscience was established to conduct multidisciplinary research in the fields of materials, electronics and biology. Scientists may be part of the Nanoscience Institute while still performing research for their respective divisions.
The main campus of NRL is in Washington, DC, near the southernmost part of the District. It is on the Potomac River and is immediately south of (but is not part of) Joint Base Anacostia-Bolling. This campus is immediately north of the Blue Plains site of the DC Water Authority. Exit 1 of northbound I-295 leads directly to Overlook Avenue and the NRL Main Gate. The U.S. Postal Service operates a post office on the NRL main campus.
In addition, NRL operates several field sites and satellite facilities:
Artifacts found on the NRL campus, such as stone tools and ceramic shards, show that the site had been inhabited since the Late Archaic Period. Cecil Calvert, 2nd Baron Baltimore granted the tract of land including the present NRL campus to William Middleton in 1663. It became part of the District of Columbia in 1791, and was purchased by Thomas Grafton Addison in 1795, who named the area Bellevue and built a mansion on the highlands to the east. Zachariah Berry purchased the land in 1827, who rented it out for various purposes including a fishery at Blue Plains. The mansion was demolished during the Civil War to build Fort Greble. In 1873 the land was purchased by the federal government as the Bellevue Annex to the Naval Gun Factory, and several buildings were constructed including the Commandant's house, "Quarters A", which is still in use today.
The Naval Research Laboratory came into existence from an idea that originated from Thomas Edison. In a May 1915 editorial piece in the New York Times Magazine, Edison wrote; "The Government should maintain a great research laboratory... In this could be developed...all the technique of military and naval progression without any vast expense."This statement addressed concerns about World War I in the United States.
Edison then agreed to serve as the head of the Naval Consulting Board that consisted of civilians who had achieved expertise. The focus of the Naval Consulting Board was as advisor to the U.S. Navy pertaining to science and technology. The board brought forward a plan to create a modern facility for the Navy. In 1916 Congress allocated $1.5 million for implementation. However, construction was delayed until 1920 because of the war and internal disagreements within the board.
The U.S. Naval Research Laboratory, the first modern research institution created within the United States Navy, began operations at 1100 on 2 July 1923. The Laboratory's two original divisions – Radio and Sound – performed research in the fields of high-frequency radio and underwater sound propagation. They produced communications equipment, direction-finding devices, sonar sets, and the first practical radar equipment built in the United States. They performed basic research, participating in the discovery and early exploration of the ionosphere. The NRL gradually worked towards its goal of becoming a broadly based research facility. By the beginning of World War II, five new divisions had been added: Physical Optics, Chemistry, Metallurgy, Mechanics and Electricity, and Internal Communications.
Total employment at the NRL jumped from 396 in 1941 to 4400 in 1946, expenditures from $1.7 million to $13.7 million, the number of buildings from 23 to 67, and the number of projects from 200 to about 900. During World War II, scientific activities necessarily were concentrated almost entirely on applied research. New electronics equipment – radio, radar, sonar – was developed. Countermeasures were devised. New lubricants were produced, as were antifouling paints, luminous identification tapes, and a sea marker to help save survivors of disasters at sea. A thermal diffusion process was conceived and used to supply some of the U-235 isotope needed for one of the first atomic bombs. Also, many new devices that developed from booming wartime industry were type tested and then certified as reliable for the Fleet.
As a result of the scientific accomplishments of the WWII, the United States emerged into the postwar era determined to consolidate its wartime gains in science and technology and to preserve the working relationship between its armed forces and the scientific community. While the Navy was establishing the Office of Naval Research (ONR) as a liaison with and supporter of basic and applied scientific research, the Navy encouraged NRL to broaden its scope since it was the Navy Department's corporate research laboratory. NRL was placed under the administrative oversight of ONR after ONR was created. NRL's Commanding Officer reports to the Navy's Chief of Naval Research (CNR). The Chief of Naval Research leads the Office of Naval Research, which primarily is located in the Ballston area of Arlington, Virginia. The reorganization also caused a parallel shift of the Laboratory's emphasis to one of long-range basic and applied research in the full range of the physical sciences.
However, rapid expansion during the war had left NRL improperly structured to address long-term Navy requirements. One major task – neither easily nor rapidly accomplished – was that of reshaping and coordinating research. This was achieved by transforming a group of largely autonomous scientific divisions into a unified institution with a clear mission and a fully coordinated research program. The first attempt at reorganization vested power in an executive committee composed of all the division superintendents. This committee was impracticably large, so in 1949, a civilian director of research was named and given full authority over the program. Positions for associate directors were added in 1954.
In 1992, the previously separate Naval Oceanographic and Atmospheric Research Laboratory (NOARL), with centers in Bay St. Louis, Mississippi, and Monterey, California, was merged into NRL. Since then, NRL is also the lead Navy center for research in Oceanographic and Atmospheric Sciences, with special strengths in physical oceanography, marine geosciences, ocean acoustics, marine meteorology, and remote oceanic and atmospheric sensing.
Frank Anthony Wilczek is an American theoretical physicist, mathematician and a Nobel laureate. He is currently the Herman Feshbach Professor of Physics at the Massachusetts Institute of Technology (MIT), Founding Director of T. D. Lee Institute and Chief Scientist Wilczek Quantum Center, Shanghai Jiao Tong University (SJTU), Distinguished Origins Professor at Arizona State University (ASU) and full Professor at Stockholm University.
Kenneth Geddes "Ken" Wilson was an American theoretical physicist and a pioneer in leveraging computers for studying particle physics. He was awarded the 1982 Nobel Prize in Physics for his work on phase transitions—illuminating the subtle essence of phenomena like melting ice and emerging magnetism. It was embodied in his fundamental work on the renormalization group.
In particle physics, majorons are a hypothetical type of Goldstone boson that are theorized to mediate the neutrino mass violation of lepton number or B − L in certain high energy collisions such as
Serguei Vladilenovich Krasnikov is a Russian physicist.
CLEO was a general purpose particle detector at the Cornell Electron Storage Ring (CESR), and the name of the collaboration of physicists who operated the detector. The name CLEO is not an acronym; it is short for Cleopatra and was chosen to go with CESR. CESR was a particle accelerator designed to collide electrons and positrons at a center-of-mass energy of approximately 10 GeV. The energy of the accelerator was chosen before the first three bottom quark Upsilon resonances were discovered between 9.4 GeV and 10.4 GeV in 1977. The fourth Υ resonance, the Υ(4S), was slightly above the threshold for, and therefore ideal for the study of, B meson production.
The Daya Bay Reactor Neutrino Experiment is a China-based multinational particle physics project studying neutrinos. The multinational collaboration includes researchers from China, Chile, the United States, Taiwan, Russia, and the Czech Republic. The US side of the project is funded by the US Department of Energy's Office of High Energy Physics.
Christopher T. Hill is an American theoretical physicist at the Fermi National Accelerator Laboratory who did undergraduate work in physics at M.I.T., and graduate work at Caltech. Hill's Ph.D. thesis, "Higgs Scalars and the Nonleptonic Weak Interactions" (1977) contains the first detailed discussion of the two-Higgs-doublet model.
Alexander Balankin is a Mexican scientist of Russian origin whose work in the field of fractal mechanics and its engineering applications won him the UNESCO Science Prize in 2005.
Ghost imaging is a technique that produces an image of an object by combining information from two light detectors: a conventional, multi-pixel detector that doesn't view the object, and a single-pixel (bucket) detector that does view the object. Two techniques have been demonstrated. A quantum method uses a source of pairs of entangled photons, each pair shared between the two detectors, while a classical method uses a pair of correlated coherent beams without exploiting entanglement. Both approaches may be understood within the framework of a single theory.
Daniel Amihud Lidar is the holder of the Viterbi Professorship of Engineering at the University of Southern California, where he is a Professor of Electrical Engineering, Chemistry, Physics & Astronomy. He is the Director and co-founder of the USC Center for Quantum Information Science & Technology (CQIST) as well as Scientific Director of the USC-Lockheed Martin Quantum Computation Center, notable for his research on control of quantum systems and quantum information processing.
Thomas Carlos Mehen is an American physicist. His research has consisted of primarily Quantum chromodynamics (QCD) and the application of effective field theory to problems in hadronic physics. He has also worked on effective field theory for non-relativistic particles whose short range interactions are characterized by a large scattering length, as well as novel field theories which arise from unusual limits of string theory.
Subir Sachdev is Herchel Smith Professor of Physics at Harvard University specializing in condensed matter. He was elected to the U.S. National Academy of Sciences in 2014, and received the Lars Onsager Prize from the American Physical Society and the Dirac Medal from the ICTP in 2018.
Nicholas Harrison FRSC FinstP is an English theoretical physicist known for his work on developing theory and computational methods for discovering and optimising advanced materials. He is the Professor of Computational Materials Science in the Department of Chemistry at Imperial College London where he is co-director of the Institute of Molecular science and Engineering.
In strong interaction physics, light front holography or light front holographic QCD is an approximate version of the theory of quantum chromodynamics (QCD) which results from mapping the gauge theory of QCD to a higher-dimensional anti-de Sitter space (AdS) inspired by the AdS/CFT correspondence proposed for string theory. This procedure makes it possible to find analytic solutions in situations where strong coupling occurs, improving predictions of the masses of hadrons and their internal structure revealed by high-energy accelerator experiments. The most widely used approach to finding approximate solutions to the QCD equations, lattice QCD, has had many successful applications; however, it is a numerical approach formulated in Euclidean space rather than physical Minkowski space-time.
Maya Paczuski is the head and founder of the Complexity Science Group at the University of Calgary. She is a well-cited physicist whose work spans self-organized criticality, avalanche dynamics, earthquake, and complex networks. She was born in Israel in 1963, but grew up in the United States. Maya Paczuski received a B.S. and M.S. in Electrical Engineering and Computer Science from M.I.T. in 1986 and then went on to study with Mehran Kardar, earning her Ph.D in Condensed matter physics from the same institute.
Modern searches for Lorentz violation are scientific studies that look for deviations from Lorentz invariance or symmetry, a set of fundamental frameworks that underpin modern science and fundamental physics in particular. These studies try to determine whether violations or exceptions might exist for well-known physical laws such as special relativity and CPT symmetry, as predicted by some variations of quantum gravity, string theory, and some alternatives to general relativity.
A time crystal or space-time crystal is a structure that repeats in time, as well as in space. Normal three-dimensional crystals have a repeating pattern in space, but remain unchanged as time passes. Time crystals repeat themselves in time as well, leading the crystal to change from moment to moment. A time crystal never reaches thermal equilibrium, as it is a type of non-equilibrium matter, a form of matter proposed in 2012, and first observed in 2017. This state of matter cannot be isolated from its environment—it is an open system in non-equilibrium.
Kam-Biu Luk is a professor of physics, with a focus on particle physics, at UC Berkeley and a senior faculty member in the Lawrence Berkeley National Laboratory's physics division. Luk has conducted research on neutrino oscillation and CP violation. Luk and his collaborator Yifang Wang were awarded the 2014 Panofsky Prize “for their leadership of the Daya Bay experiment, which produced the first definitive measurement of θ13 angle of the neutrino mixing matrix.” His work on neutrino oscillation also received 2016 Breakthrough Prize in Fundamental Physics shared with other teams. Luk is a fellow of the American Physical Society.
Quantum machine learning is an emerging interdisciplinary research area at the intersection of quantum physics and machine learning. The most common use of the term refers to machine learning algorithms for the analysis of classical data executed on a quantum computer. While machine learning algorithms are used to compute immense quantities of data, quantum machine learning increases such capabilities intelligently, by creating opportunities to conduct analysis on quantum states and systems. This includes hybrid methods that involve both classical and quantum processing, where computationally difficult subroutines are outsourced to a quantum device. These routines can be more complex in nature and executed faster with the assistance of quantum devices. Furthermore, quantum algorithms can be used to analyze quantum states instead of classical data. Beyond quantum computing, the term "quantum machine learning" is often associated with machine learning methods applied to data generated from quantum experiments, such as learning quantum phase transitions or creating new quantum experiments. Quantum machine learning also extends to a branch of research that explores methodological and structural similarities between certain physical systems and learning systems, in particular neural networks. For example, some mathematical and numerical techniques from quantum physics are applicable to classical deep learning and vice versa. Finally, researchers investigate more abstract notions of learning theory with respect to quantum information, sometimes referred to as "quantum learning theory".
Spin squeezing is a quantum process that decreases the variance of one of the angular momentum components in an ensemble of particles with a spin. The quantum states obtained are called spin squeezed states. Such states can be used for quantum metrology, as they can provide a better precision for estimating a rotation angle than classical interferometers.
