Depending on whether this system is quantum or not, the correlations between the series of measurement outcomes on each member of the pair would be different. This test aims to simultaneously measure the state of two particles created together. In 1964, British scientist John Bell devised a theoretical test to verify this prediction, which Albert Einstein did not believe in. The measurement of one of the member's properties immediately influences the measurement of its counterpart. It is impossible to consider the two elements of the pair as independent. It is possible that, under certain conditions, two particles remain linked by an invisible thread, even if they are separated by several kilometers. Aspect, then a thesis student at the University of Orsay, showed in 19, by means of delicate experiments now in all physics books, that it was nevertheless quite real. We are interested in your experience using the site.

It is based on at least two oddities: The fact that particles are both waves and material objects, allowing them to pass for example through two places at the same time and that the energies of these systems are not continuous but "quantized," as if it were only possible to climb a slope by jumps, stairs or a ladder. It allows geolocation by satellite thanks to high-precision clocks. It also gave birth to lasers and hard disks. Its first revolution led to the invention of transistors, electronic chips, computers and cell phones. This quantum theory, developed during the inter-war period, describes the world of matter, its particles, atoms and molecules.
Aspect himself likes to call the "second quantum revolution." This revolution opens a gateway to a strange, microscopic world, as well as to unexpected and spectacular applications. The prize honors the trailblazers of what Mr. The researcher shares the famous distinction with American scientist John Clauser, 79, and Austria's Anton Zeilinger, 76, as a reward for "experiments with entangled photons, establishing the violation of Bell's inequalities and pioneering quantum information science." The Swedish Academy finally decided on Tuesday, October 4, to reward the emeritus director of research at France's National Center for Scientific Research (CNRS) and professor at the prestigious Ecole Polytechnique. The question was not whether 75-year-old Frenchman Alain Aspect would win the Nobel Prize in Physics, but when and with whom. Subscribers only Alain Aspect during the presentation of the Niels Bohr Medal by Queen Marguerite II of Denmark, in Copenhagen, in 2013. The Frenchman was honored jointly with the American John Clauser and the Austrian Anton Zeilinger for the discovery of particle entanglement, opening the way to applications in quantum information.īy David Larousserie Published on Octoat 16h34 4, 2022.Physics Nobel Prize awards Alain Aspect, pioneer of the 'second quantum revolution'
Clauser and Anton Zeilinger, during a news conference at The Royal Swedish Academy of Sciences in Stockholm, Sweden, on Oct. Secretary General of the Royal Swedish Academy of Sciences Hans Ellegren, Eva Olsson and Thors Hans Hansson, members of the Nobel Committee for Physics announce the winners of the 2022 Nobel Prize in Physics: Alain Aspect, John F. The money comes from a bequest left by the prize's creator, Swedish inventor Alfred Nobel, who died in 1895. The prizes carry a cash award of 10 million Swedish kronor (nearly $900,000) and will be handed out on Dec. The 2022 Nobel Peace Prize will be announced on Friday and the economics award on Oct. They continue with chemistry on Wednesday and literature on Thursday. 2 days ago &0183 &32 Clauser, 79, was awarded his share of the prize for a 1972 experiment, cobbled together with scavenged equipment, that helped settle a famous debate about quantum mechanics between Einstein and. A week of Nobel Prize announcements kicked off Monday with Swedish scientist Svante Paabo receiving the award in medicine Monday for unlocking secrets of Neanderthal DNA that provided key insights into our immune system.
