Reona Esaki, also known as Leo Esaki, is a Japanese physicist who shared the Nobel Prize in Physics in 1973 with Ivar Giaever and Brian David Josephson for his work in electron tunneling in semiconductor materials which finally led to his invention of the Esaki diode, which exploited that phenomenon. This research was done when he was with Tokyo Tsushin Kogyo. He has also contributed in being a pioneer of the semiconductor superlattices.
Daniel Chee Tsui is a Chinese-born American physicist, Nobel laureate, and the Arthur Legrand Doty Professor of Electrical Engineering, Emeritus, at Princeton University. Tsui's areas of research include electrical properties of thin films and microstructures of semiconductors and solid-state physics.
Superconducting quantum computing is a branch of solid state quantum computing that implements superconducting electronic circuits using superconducting qubits as artificial atoms, or quantum dots. For superconducting qubits, the two logic states are the ground state and the excited state, denoted respectively. Research in superconducting quantum computing is conducted by companies such as Google, IBM, IMEC, BBN Technologies, Rigetti, and Intel. Many recently developed QPUs utilize superconducting architecture.
Nuclear magnetic resonance quantum computing (NMRQC) is one of the several proposed approaches for constructing a quantum computer, that uses the spin states of nuclei within molecules as qubits. The quantum states are probed through the nuclear magnetic resonances, allowing the system to be implemented as a variation of nuclear magnetic resonance spectroscopy. NMR differs from other implementations of quantum computers in that it uses an ensemble of systems, in this case molecules, rather than a single pure state.
Sankar Das Sarma is an India-born American theoretical condensed matter physicist, who has worked in the broad research topics of theoretical physics, condensed matter physics, statistical mechanics, quantum physics, and quantum information. He has been a member of the Department of Physics at University of Maryland, College Park since 1980.
The spin qubit quantum computer is a quantum computer based on controlling the spin of charge carriers in semiconductor devices. The first spin qubit quantum computer was first proposed by Daniel Loss and David P. DiVincenzo in 1997, also known as the Loss–DiVincenzo quantum computer. The proposal was to use the intrinsic spin-½ degree of freedom of individual electrons confined in quantum dots as qubits. This should not be confused with other proposals that use the nuclear spin as qubit, like the Kane quantum computer or the nuclear magnetic resonance quantum computer.
Yoshihisa Yamamoto is the director of Physics & Informatics Laboratories, NTT Research, Inc. He is also Professor (Emeritus) at Stanford University and National Institute of Informatics (Tokyo).
The Nevill Mott Medal and Prize is an award presented in selected years by the Institute of Physics in the United Kingdom, for distinguished research in condensed matter or materials physics. It was first established in 1997 thanks to a donation from Sir Nevill Mott's family. Sir Nevill Mott was one of the outstanding British condensed matter theorists and won a Nobel Prize in Physics in 1977. He died in 1996. The award consists of a silver medal and a prize of £1000.
Steven M. Girvin is an American physicist who is the Eugene Higgins Professor of Physics at Yale University and who served as deputy provost for research at Yale from 2007 to 2017. Girvin is noted for his theoretical work on quantum many body systems such as the fractional quantum Hall effect, and as co-developer of circuit QED, the application of the ideas of quantum optics to superconducting microwave circuits. Circuit QED is now the leading architecture for construction of quantum computers based on superconducting qubits.
Shoucheng Zhang was a Chinese-American physicist who was the JG Jackson and CJ Wood professor of physics at Stanford University. He was a condensed matter theorist known for his work on topological insulators, the quantum Hall effect, the quantum spin Hall effect, spintronics, and high-temperature superconductivity. According to the National Academy of Sciences:
He discovered a new state of matter called topological insulator in which electrons can conduct along the edge without dissipation, enabling a new generation of electronic devices with much lower power consumption. For this ground breaking work he received numerous international awards, including the Buckley Prize, the Dirac Medal and Prize, the Europhysics Prize, the Physics Frontiers Prize and the Benjamin Franklin Medal.
Laurens W. Molenkamp is a professor of physics and Chair of Experimental Physics at the University of Würzburg. He is known for his work on semiconductor structures and topological insulators.
Duncan G. Steel is an American experimental physicist, researcher and professor in quantum optics in condensed matter physics. He is the Robert J. Hiller Professor of Electrical Engineering, Professor of Physics, Professor of Biophysics, and Research Professor in the Institute of Gerontology at the University of Michigan. Steel is also a Guggenheim Scholar and a Fellow of American Physical Society, the Optical Society of America, and the Institute of Electrical and Electronics Engineers. He coedited the five-volume series on the Encyclopedia of Modern Optics.
David P. DiVincenzo is an American theoretical physicist. He is the director of the Institute of Theoretical Nanoelectronics at the Peter Grünberg Institute at the Forschungszentrum Jülich and Professor at the Institute for Quantum Information at RWTH Aachen University. With Daniel Loss, he proposed the Loss–DiVincenzo quantum computer in 1997, which would use electron spins in quantum dots as qubits.
The DiVincenzo criteria are conditions necessary for constructing a quantum computer, conditions proposed in 2000 by the theoretical physicist David P. DiVincenzo, as being those necessary to construct such a computer—a computer first proposed by mathematician Yuri Manin, in 1980, and physicist Richard Feynman, in 1982—as a means to efficiently simulate quantum systems, such as in solving the quantum many-body problem.
Andreas Wallraff is a German physicist who conducts research in quantum information processing and quantum optics. He has taught as a professor at ETH Zürich in Zürich, Switzerland since 2006. He worked as a research scientist with Robert J. Schoelkopf at Yale University from 2002 to 2005, during which time he performed experiments in which the coherent interaction of a single photon with a single quantum electronic circuit was observed for the first time. His current work at ETH Zürich focuses on hybrid quantum systems combining superconducting electronic circuits with semiconductor quantum dots and individual Rydberg atoms as well as quantum error correction with superconducting qubits.
In quantum computing, a qubit is a unit of information analogous to a bit in classical computing, but it is affected by quantum mechanical properties such as superposition and entanglement which allow qubits to be in some ways more powerful than classical bits for some tasks. Qubits are used in quantum circuits and quantum algorithms composed of quantum logic gates to solve computational problems, where they are used for input/output and intermediate computations.
