The “Spooky” Quantum Scientists who won the Nobel Prize in Physics

Researchers in the “spooky” field of quantum Scientists have won the Nobel Prize in Physics.

Stockholm: Scientists Alain Aspect, John Clauser, and Anton Zeilinger won the 2022 Nobel Prize in Physics for their advances in quantum mechanics on the behavior of subatomic particles, opening the door to work on supercomputers and encrypted communications.

The awarding body said on Tuesday that the prizes were awarded for “experiments with entangled photons, which demonstrate the violation of Bell’s inequality and are pioneers in quantum information science.”

The Royal Swedish Academy of Sciences said the prize winners – a French Aspect, a US Closer, and an Austrian Zeilinger – have enabled more basic research and are also likely to pave the way for practical new technology.

Scientists have all performed experiments on quantum entanglement, in which two particles stick together regardless of the distance between them, an area that preoccupied Albert Einstein himself, who he once referred to in a letter as “terrifying action at a distance.”

“It was nice to get the phone call from him about an hour ago and I’m still a little shaken, but I’m very positive so thank you very much,” Zeilinger said in a conference call.

“I must say that I have always been interested in quantum mechanics from the first moment I read about it. Suddenly some theoretical predictions struck me because they didn’t fit all the usual intuition one might have.”

In lead articles explaining the award, the Academy said the laureates’ work includes “the mind-boggling insight that quantum mechanics allows a single quantum system to be split into parts that are separate from each other but still function as one.” Unit”. ”

“This goes against all the usual ideas about cause and effect and the nature of reality.”

Encrypted Connection

As a result of their work, the academy said, the use of “the special properties of single-particle systems to build quantum computers, improve measurements, build quantum networks and create secure quantum encrypted communication” was being developed.

The prize winners have discovered in pioneering experiments how two or more photons, or light particles, “entangled” because they come from the same laser beam, interact even when they are very far from each other.

Dating back more than a century and worth 10 million Swedish kronor (US$902,315), the prize was awarded by the Royal Swedish Academy of Scientists.

Physics is the second Nobel Prize awarded this week after Swedish geneticist Svante Pappo won the Physiology or Medicine prize on Monday.

The most prestigious prizes for achievements in science, literature, and peace were created by the will of Alfred Nobel, who made a fortune with his invention of dynamite and have been awarded since 1901 with some interruptions, especially during the two world wars.

The Physics Prize has often taken center stage among the prizes, featuring familiar Scientist names such as Albert Einstein, Max Planck, Pierre Curie, and Marie Curie, rewarding breakthroughs that changed our view of the world.

Last year, scientists Siokoro Manabe, Klaus Haselmann, and Giorgio Parisi shared the Physics Prize for their work on complex physical systems such as Earth’s climate change, which is key to understanding global warming.

The Physics Prize was announced over consecutive weekdays in early October, and the Physics Prize announcement would be followed by prizes for Chemistry, Literature, Peace, and Economics, the latter being added in 1969 to the original lineup.
