Alain Aspect (Шаблон:IPA-fr; born 15 June 1947[1]) is a French physicist noted for his experimental work on quantum entanglement.[2][3][4][5]

Aspect was awarded the 2022 Nobel Prize in Physics, jointly with John Clauser and Anton Zeilinger, "for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science".Шаблон:R

Education

Шаблон:Main Aspect is a graduate of the École Normale Supérieure de Cachan (ENS Cachan, today part of Paris-Saclay University).[6] He passed the agrégation in physics in 1969 and received his PhD degree in 1971 from the École supérieure d'optique (later known as Institut d'Optique Graduate School) of Université d'Orsay (later known as Université Paris-Sud). He then taught for three years in Cameroon as a replacement for then compulsory military service.[7]

In the early 1980s, while working on his doctorat d'État (habilitation thesis),[8] he performed the Bell test experiments that showed that Albert Einstein, Boris Podolsky and Nathan Rosen's putative reductio ad absurdum of quantum mechanics, namely that it implied 'ghostly action at a distance', did in fact appear to be realized when two particles were separated by an arbitrarily large distance (see EPR paradox and Aspect's experiment). A correlation between the particles' wave functions remains, as long as they were once part of the same undisturbed wave function before one of the child particles was measured. He defended his doctorat d'État in 1983 at Université Paris-Sud (today part of Paris-Saclay University).[9]

Aspect received an honorary doctorate from Heriot-Watt University in 2008.[10]

Research

Aspect's experiments, following the first experiment of Stuart Freedman and John Clauser in 1972, were considered to provide further support to the thesis that Bell's inequalities are violated in its CHSH version, in particular by closing a form of the locality loophole. However, his results were not completely conclusive since there were loopholes that allowed for alternative explanations that comply with local realism.[11]

After his work on Bell's inequalities, Aspect turned toward studies of laser cooling of neutral atoms, and Bose–Einstein condensates at the Kastler-Brossel Laboratory.[12]

Aspect was deputy director of the French "grande école" École supérieure d'optique until 1994. He is a member of the French Academy of Sciences and French Academy of Technologies, and a professor at the École Polytechnique.[6]

Distinctions

Aspect was elected a Foreign Member of the Royal Society (ForMemRS) in 2015.[13] His certificate of election reads Шаблон:Quote

In 2005 he was awarded the gold medal of the Centre national de la recherche scientifique, where he is Research Director. The 2010 Wolf Prize in physics was awarded to Aspect, Anton Zeilinger and John Clauser. In 2013 Aspect was awarded both the Niels Bohr International Gold Medal and the UNESCO Niels Bohr Medal. In 2011, he was assigned the Medal of the City of Paris. In 2013, he was also awarded the Balzan Prize for Quantum Information Processing and Communication. In 2014, he was named Officer of the Legion of Honour.[14]

Asteroid 33163 Alainaspect, discovered by astronomers at Caussols in 1998, was named after him.[15] The official Шаблон:MoMP was published by the Minor Planet Center on 8 November 2019 (Шаблон:Small).[16]

Aspect was awarded the 2022 Nobel Prize in Physics alongside John F. Clauser and Anton Zeilinger "for experiments with entangled photons, establishing the violation of Bell's inequalities and pioneering quantum information science".[17]
