Serge Haroche (born 11 September 1944) [1] is a French physicist who was awarded the 2012 Nobel Prize for Physics jointly with David J. Wineland for "ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems", a study of the particle of light, the photon. [2] [3] [4] This and his other works developed laser spectroscopy. Since 2001, Haroche is a Professor at the Collège de France and holds the Chair of Quantum Physics. In 1971 he defended his doctoral thesis in physics at the University of Paris VI, his research has been conducted under the direction of Claude Cohen-Tannoudji. [5]


Personal life and family

Serge Haroche was born in Casablanca, Morocco, to Albert Haroche (1920–1998), from a Moroccan Jewish family, and Valentine Haroche, née Roubleva (1921–1998) a teacher who was born in Odessa to a Jewish family of physicians who relocated to Morocco in the early 1920s. His father, a lawyer trained in Rabat, was one of seven children born to a family of teachers (Isaac and Esther Haroche) who worked at the École de l’Alliance israélite (AIU). [6] [7] [8] [9] [10] [11] [12] Both paternal grandparents of Serge Haroche had been AIU students in their respective hometowns of Marrakesh and Tétouan (the school which Esther Azerad attended in Tétouan had been founded in 1862; it was the first school of the AIU network). [13]

Haroche left Morocco and settled in France in 1956, at the end of the French protectorate treaty.

He currently lives in Paris; he is married to the sociologist Claudine Haroche (née Zeligson), also descending from the Russian Jewish émigrés family, with two children (aged 40 and 43). [14] [15] [16] He is the uncle of French singer–songwriter and actor Raphaël Haroche (known as Raphaël, his stage name). [17]


Haroche worked in the Centre national de la recherche scientifique (CNRS) as a research scientist from 1967 to 1975, and spent a year (1972–1973) as a visiting post-doc in Stanford University, in Arthur Leonard Schawlow's team. In 1975 he moved to a professor position at Paris VI University. At the same time he taught in other institutions, in particular at the École polytechnique (1973–1984), MIT (1980), Harvard University (1981), Yale University (1984–1993) and Conservatoire national des arts et métiers (2000). He was head of the Physics department at the École normale supérieure from 1994 to 2000.

Since 2001, Haroche has been a Professor at the Collège de France and holds the Chair of Quantum Physics. He is a member of the Société Française de Physique, the European Physical society and a fellow and member of the American Physical Society.

In September 2012, Serge Haroche was elected by his peers to the position of administrator of the Collège de France.

On 9 October 2012 Haroche was awarded the Nobel Prize in Physics, together with the American physicist David Wineland, for their work regarding measurement and manipulation of individual quantum systems.

Haroche works primarily in atomic physics and quantum optics. [18] [19] [20] [21] [22] [23] [24] He is principally known for proving quantum decoherence by experimental observation, while working with colleagues at the École normale supérieure in Paris in 1996.

After a PhD dissertation on dressed atoms under the supervision of Claude Cohen-Tannoudji (himself a Nobel Prize recipient) from 1967 to 1971, he developed new methods for laser spectroscopy, based on the study of quantum beats and superradiance. He then moved on to Rydberg atoms, giant atomic states particularly sensitive to microwaves, which makes them well adapted for studying the interactions between light and matter. He showed that such atoms, coupled to a superconducting cavity containing a few photons, are well-suited to the testing of quantum decoherence and to the realization of quantum logic operations necessary for the treatment of quantum information.

Wave–particle duality is the concept in quantum mechanics that every particle or quantum entity may be described as either a particle or a wave. It expresses the inability of the classical concepts "particle" or "wave" to fully describe the behaviour of quantum-scale objects. As Albert Einstein wrote:

It seems as though we must use sometimes the one theory and sometimes the other, while at times we may use either. We are faced with a new kind of difficulty. We have two contradictory pictures of reality; separately neither of them fully explains the phenomena of light, but together they do.

Atomic electron transition is a change of an electron from one energy level to another within an atom or artificial atom. It appears discontinuous as the electron "jumps" from one energy level to another, typically in a few nanoseconds or less. It is also known as an electronic (de-)excitation or atomic transition or quantum jump.

Laser cooling variety of techniques where atomic samples are cooled via interacting with lasers

Laser cooling refers to a number of techniques in which atomic and molecular samples are cooled down to near absolute zero. Laser cooling techniques rely on the fact that when an object absorbs and re-emits a photon its momentum changes. For an ensemble of particles, their thermodynamic temperature is proportional to the variance in their velocity. That is, more homogeneous velocities among particles corresponds to a lower temperature. Laser cooling techniques combine atomic spectroscopy with the aforementioned mechanical effect of light to compress the velocity distribution of an ensemble of particles, thereby cooling the particles.

Quantum optics (QO) is a field of research that uses semi-classical and quantum-mechanical physics to investigate phenomena involving light and its interactions with matter at submicroscopic levels. In other words, it is quantum mechanics applied to photons or light.

Trapped ion quantum computer Proposed quantum computer implementation

A trapped ion quantum computer is one proposed approach to a large-scale quantum computer. Ions, or charged atomic particles, can be confined and suspended in free space using electromagnetic fields. Qubits are stored in stable electronic states of each ion, and quantum information can be transferred through the collective quantized motion of the ions in a shared trap. Lasers are applied to induce coupling between the qubit states or coupling between the internal qubit states and the external motional states.

Quantum networks form an important element of quantum computing and quantum communication systems. Quantum networks facilitate the transmission of information in the form of quantum bits, also called qubits, between physically separated quantum processors. A quantum processor is a small quantum computer being able to perform quantum logic gates on a certain number of qubits. Quantum networks work in a similar way to classical networks. The main difference, as will be detailed more in later paragraphs, is that quantum networking like quantum computing is better at solving certain problems, such as modeling quantum systems.

Doppler cooling laser cooling technique

Doppler cooling is a mechanism that can be used to trap and slow the motion of atoms to cool a substance. The term is sometimes used synonymously with laser cooling, though laser cooling includes other techniques.

Cavity quantum electrodynamics is the study of the interaction between light confined in a reflective cavity and atoms or other particles, under conditions where the quantum nature of light photons is significant. It could in principle be used to construct a quantum computer.

David J. Wineland American physicist

David Jeffrey Wineland is an American Nobel-laureate physicist at the National Institute of Standards and Technology (NIST) physics laboratory. His work has included advances in optics, specifically laser cooling trapped ions and using ions for quantum computing operations. He was awarded the 2012 Nobel Prize in Physics, jointly with Serge Haroche, for "ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems".

H. Jeff Kimble, is the William L. Valentine Professor and Professor of Physics at Caltech. His research is in quantum optics and is noted for groundbreaking experiments in physics including one of the first demonstrations of teleportation of a quantum state, quantum logic gate, and the development of the first single atom laser. According to Elizabeth Rogan, OSA CEO, "Jeff has led a revolution in modern physics through his pioneering research in the coherent control of the interactions of light and matter." Kimble's main research focus is in quantum information science and the quantum dynamics of open systems.

Circuit quantum electrodynamics provides a means of studying the fundamental interaction between light and matter. As in the field of cavity quantum electrodynamics, a single photon within a single mode cavity coherently couples to a quantum object (atom). In contrast to cavity QED, the photon is stored in a one-dimensional on-chip resonator and the quantum object is no natural atom but an artificial one. These artificial atoms usually are mesoscopic devices which exhibit an atom-like energy spectrum. The field of circuit QED is a prominent example for quantum information processing and a promising candidate for future quantum computation.

Single-photon sources are light sources that emit light as single particles or photons. They are distinct from coherent light sources (lasers) and thermal light sources such as incandescent light bulbs. The Heisenberg uncertainty principle dictates that a state with an exact number of photons of a single frequency cannot be created. However, Fock states can be studied for a system where the electric field amplitude is distributed over a narrow bandwidth. In this context, a single-photon source gives rise to an effectively one-photon number state. Photons from an ideal single-photon source exhibit quantum mechanical characteristics. These characteristics include photon antibunching, so that the time between two successive photons is never less than some minimum value. This is normally demonstrated by using a beam splitter to direct about half of the incident photons toward one avalanche photodiode, and half toward a second. Pulses from one detector are used to provide a ‘counter start’ signal, to a fast electronic timer, and the other, delayed by a known number of nanoseconds, is used to provide a ‘counter stop’ signal. By repeatedly measuring the times between ‘start’ and ‘stop’ signals, one can form a histogram of time delay between two photons and the coincidence count- if bunching is not occurring, and photons are indeed well spaced, a clear notch around zero delay is visible.

Einstein Prize for Laser Science award

The Einstein Prize for Laser Science was a recognition awarded by the former Society for Optical and Quantum Electronics and sponsored by the Eastman Kodak Company. The prize, awarded in the 1988–1999 period, consisted of a 3-inch brass medal including Einstein's image and a depiction of a two-level transition including the A and B coefficients. Recipients of the prize include:

Jaynes–Cummings–Hubbard model model in quantum optics

The Jaynes-Cummings-Hubbard (JCH) model is a many-body quantum system modeling the quantum phase transition of light. As the name suggests, the Jayne-Cummings-Hubbard model is a variant on the Jaynes–Cummings model; a one-dimensional JCH model consists of a chain of N coupled single-mode cavities, each with a two-level atom. Unlike in the competing Bose-Hubbard model, Jayne-Cummings-Hubbard dynamics depend on photonic and atomic degrees of freedom and hence require strong-coupling theory for treatment. One method for realizing an experimental model of the system uses circularly-linked superconducting qubits.

Photonic molecules are a theoretical natural form of matter which can also be made artificially in which photons bind together to form "molecules". They were first predicted in 2007. Photonic molecules are formed when individual (massless) photons "interact with each other so strongly that they act as though they have mass". In an alternative definition, photons confined to two or more coupled optical cavities also reproduce the physics of interacting atomic energy levels, and have been termed as photonic molecules.
