Nobel Prize in Physics 2022: Three scientists recognized for their experiments on entangled photons and their breakthroughs in quantum information

The Nobel Prize in Physics It was Scientists Alain Aspect, from France; John F. Glaser, from the United States; and Anton Zeilinger, from Austria, the Royal Swedish Academy of Sciences announced on Tuesday. All three of them were approved Experiments with entangled photons and Their contributions to the development of new technologies based on quantum information.

“This award is an inspiration to the youth: this award would not have been possible without the more than 100 young people who have worked with me over the years,” Jeilinger said during a press conference after his name was announced.

“It has become increasingly clear that a new type of quantum technology is emerging. Beyond fundamental questions about the interpretation of quantum mechanics, we can see that the work of laureates with complex levels is very important,” Anders Irbach, chairman of the Nobel Committee for Physics, announced the three winners.

The choice of winning theme comes at a time when the inexplicable effects of quantum mechanics are beginning to find applications. In fact, there is now a large field of research including quantum computers, quantum networks and secure quantum encrypted communication, the Swedish Academy said in a statement.

A key factor in this development is how quantum mechanics allows two or more so-called particles to exist. An interlocking condition. What happens to one of the particles in the entangled pair determines what happens to the other particles, even if they are far apart. For a long time, the question was whether interaction was caused by particles in an entangled pair with latent variables.

In his investigation, Glaser deepened the ideas of John Bell, who developed a mathematical inequality that led to a practical experiment. When he took the measurements, The scientist confirmed that a theory using hidden variables cannot change quantum mechanics. Aspect, meanwhile, was able to change measurement settings after the interconnected pair left its source, so the settings they had when they were broadcast didn’t affect the result.

With these tools and a long series of experiments, Zeilinger began to exploit entangled quantum states. Among other things, his research group demonstrated a phenomenon called quantum teleportation, which makes it possible to move a quantum state from one particle to another over a distance.

Aspect was born in Agen, France in 1947; He is a professor at the University of Paris-Saclay and at the Palaiseau Polytechnic School. Glaser, for his part, was born in Pasadena, USA in 1942, and is a research physicist. Zeilinger, born in 1945 in Riet im Increase, Austria, is a professor at the University of Vienna.

Last year, scientists Chiukuro Manabe, Klaus Hasselmann and Giorgio Parisi received the award for their understanding of complex systems used to study climate.

The Nobel Prize includes a cash prize of 10 million Swedish kroner (nearly $900,000) and is presented at a ceremony on December 10. The money comes from funds left by the creator of the Nobel Prize, Swedish inventor Alfred, who died in 1985.

Yesterday, the first day of these awards, the Swedish scientist Svante Pabo 67 years old Prize winner Nobel Prize in Medicine For his discoveries about human evolution, Neanderthals have unlocked the secrets of DNA, helped us understand what makes humans unique, and provided new insights into our immune systems, including our vulnerability to severe Covid.

“Through his pioneering research, Pääbo accomplished the seemingly impossible: sequencing the Neanderthal genomeAn extinct relative of modern humans,” the Nobel committee announced its decision.
