stockholmThe Nobel Prize in Physics rewards quantum technology
The prize is awarded to Frenchman Alain Aspect, American John Clauser and Austrian Anton Zeilinger who have developed tools to manipulate and manage quantum states.
The Nobel Prize in Physics was crowned Tuesday the Frenchman Alain Aspect, the American John Clauser and the Austrian Anton Zeilinger, three pioneers of the revolutionary mechanisms of quantum physics.
The three septuagenarians are rewarded for their discoveries on “quantum entanglement”, a mechanism where two quantum particles are perfectly correlated, whatever the distance which separates them, announced the Nobel jury.
The demonstration of this astonishing property has paved the way for new technologies in quantum computing and ultra-secure communications, or even ultra-sensitive quantum sensors that would allow extremely precise measurements, such as that of gravity in space. .
The trio are rewarded “for their experiments with entangled photons, establishing violations of Bell’s inequalities and opening a pioneering path towards quantum computing”, according to the Nobel jury. “Alain Aspect, John Clauser and Anton Zeilinger have each conducted groundbreaking experiments using entangled quantum states, where two particles behave as a single unit even when separated,” he explains.
Even Einstein didn’t believe it
This puzzling mechanics was predicted by quantum theory. Yet even Albert Einstein did not believe it: two particles joined at the start (like twins could be) could keep the mark of their common past and behave similarly, at a distance.
Affiliated with the French University of Paris-Saclay, Alain Aspect is 75, while John Clauser of Columbia University is 79 and Anton Zeilinger of the University of Vienna is 77. The prize is endowed with 10 million Swedish crowns (910,000 francs) in each discipline, possibly to be shared in the event of co-winners.
On Monday, the Nobel Prize in Medicine or Physiology was awarded to Swedish Svante Pääbofather of Denisova man, of paleogenomics and discoverer of Neanderthal man DNA.
The Nobel science ball ends on Wednesday with the announcement of the Nobel Prize in Chemistry to continue with the Nobel Prize in Literature on Thursday and the Nobel Peace Prize, awarded in Oslo. The Nobel series will end next Monday with the Nobel Prize in Economics.
