Biography

edit

Gershon Kurizki was born in 1952 in Vilnius, Lithuania (then the Soviet Union).[2] He immigrated to Israel with his family in 1960. After completing his B.Sc. and M.Sc. in physics at the Technion in 1979, he moved in 1980 to the University of New Mexico, USA, where he obtained his Ph. D in physics in 1983.[3] His doctoral thesis, written under the supervision of Marlan Scully and John McIver, was on radiation from fast charged particles in crystals.

He was appointed lecturer at Tel Aviv University in 1983.[2] He subsequently moved to the Weizmann Institute where he was appointed senior scientist in 1987, associate professor with tenure in 1991 and professor in 1997.[4] From 1996 to 2024 he held the Dunne Professorial Chair in Quantum Optics at the Weizmann Institute. Throughout the years, he served as visiting professor at the Universities of Aarhus in Denmark, Ulm and Heidelberg in Germany, and Shanghai in China.[4]

Gershon Kurizki is married to Zipora (Zipi, nee Zmishlany). He has two sons, Naham (b. 1978) and Yodan (b. 1986).[2]

Research

edit

Quantum Zeno and Anti-Zeno control

edit

Kurizki and coworkers developed a theory of decay and decoherence control[5][6] that exploits two opposing universal effects. One is the quantum Zeno effect (QZE) of decay slowdown, whereas the other one is its inverse, the anti-Zeno effect (AZE) of decay speedup.[7] They showed that both effects, originally thought to be caused by frequent measurements of the system, arise under any form of frequent control. Their discovery of occurrence of the AZE was deemed counterintuitive and referred to as “a watched pot boils quicker”.[8] In their theory, both the QZE and the AZE are obtained from the universal Kofman-Kurizki (KK) formula for decay and decoherence control, which has been experimentally tested in diverse systems and has influenced the development of control strategies in quantum information processing. This formula has shown that the QZE is key to the protection of quantum information from decoherence, whereas the AZE can facilitate the resetting of an open quantum system to its initial state following a quantum operation.

Control of quantum thermodynamics

edit

Kurizki and coworkers showed the ability to control via the QZE and the AZE the temperature and entropy of open quantum systems:[9] the QZE has been shown to heat up the system and the AZE to cool it down. This approach, referred to as “frequent measurements turn up the heat”,[10][11] has been employed to cool down (purify) thermal nuclear spin ensembles in solids.[12][13]

Kurizki and coworkers worked on the thermodynamics of quantum systems under frequent control. As part of this approach they proposed the (minimal) quantum heat engine or refrigerator based on a single two-level atom.[14] They showed that if the energy is supplied to the engine by a non-thermal bath, the engine efficiency can surpass the canonical Carnot limit and not adhere to the second law of thermodynamics.[15] They recently proposed a heat engine based on a nonlinear optical device that operates, unlike all existing heat engines, as a fully coherent, closed system.[16]

Quantum noise sensing under control

edit

Kurizki and coworkers developed an approach to quantum sensing that eludes the customary definitions of signal and noise. Unlike traditional sensing that aims at suppressing noise while retaining noise-free signals, their sensing focuses on bath-induced noise recorded by a quantum probe under frequent control. They showed that such noise carries information which can identify the processes that generate the noise.[17] This noise-sensing approach is finding growing applications in biomedical diagnostics. Their colloquial summary of this approach is “the bath is more a friend than a foe”.

Quantum hybrid systems

edit

Kurizki developed an approach that is being increasingly employed in quantum information processing – the use of quantum hybrid systems consisting of diverse modules, each performing a specific task suited for the advantageous functionality of that module.[18]

Engineering macroscopic forces by quantum electrodynamics

edit

Kurizki and coworkers showed that macroscopic forces between dipoles can be “engineered” by controlling the geometry of the quantum vacuum bath that confines them. Their notable discoveries within this approach include the generation of gravitational-like interactions in ultracold gases[18] and giant long-range interactions of photons or dipoles in waveguides.[19][20] These indicate that quantum electrodynamic effects, commonly associated with atomic scales, can be manifested and controlled also at macroscopic scales.[21]

Measurements for probing and engineering quantum states and correlations

edit

Kurizki and coworkers explored measuring the state of one of two coupled quantum systems as a means of engineering the state of the other. They showed that arbitrary quantum states of a light beam can be engineered by measuring atoms coupled to it[22] or by counting the photons of another light beam correlated to it.[23] They developed methods for measuring and quantifying quantum correlations of the kind discovered by Einstein, Podolsky and Rosen (EPR) in cold gases.[24]
