The 2022 Nobel Prize in Physics: Three scientists are honored for their experiments with entangled photons and their advances in quantum information

The Nobel Prize in Physics was for Scientists Alain Aspect of France. John F. Clauser from the United States. And Anton Zeilinger, of Austria, the Royal Swedish Academy of Sciences announced on Tuesday. All three have been identified Experiments with entangled photons and Their contributions to the development of new technologies are based on quantitative information.

“This award is an encouragement to young people: the award would not be possible without the more than 100 young people who have worked with me over the years,” Zeilinger said during the press conference after being known by his name.

“It is becoming increasingly clear that a new type of quantum technology is emerging. We can see that the work of the entangled state winners is of great importance, even beyond basic questions about the interpretation of the mechanics of the trio,” said Anders Erbach, chair of the Nobel Committee for Physics, announcing the trio winners. Quantum”.

The selection of the winning topic comes at a time when the untold influences of quantum mechanics are beginning to find applications. The Swedish Academy said in a statement that in fact there is now a large field of research including quantum computers, quantum networks, and secure quantum encrypted communications.

A key factor in this development is how quantum mechanics allows two or more particles to exist in what is called tangled state. What happens to one particle in an entangled pair determines what happens to the other particle, even if they are far apart. For a long time, the question has been whether the correlation is caused by the particles in an entangled pair containing hidden variables.

In his investigations, Clauser deepened the ideas of John Bell, who developed mathematical inequality, which led to practical experiment. when taking measurements, The scientist emphasized that quantum mechanics cannot be replaced by a theory that uses hidden variables. In the meantime, Aspect was able to change the scaling settings after the interlaced pair left its source, so the settings that were there when it was broadcast could not affect the result.

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

Aspect was born in 1947 in Agen, France. He is a professor at the University of Paris-Saclay and at the Palaiseau Polytechnic. Clauser, for his part, was born in 1942 in Pasadena, United States, and is a research physicist. and Zeilinger, born in 1945 in Reed im Inkris, Austria, is a professor at the University of Vienna.

Last year, scientists Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi were honored with this award for their contributions to the understanding of complex systems applied to the study of climate.

The Nobel Prize includes 10 million Swedish kronor (approximately $900,000) in cash, and is awarded at a ceremony on December 10. The money comes from a fund left by the prize’s creator, Swedish inventor Alfred Nobel, who died in 1985.

Yesterday, on the first day of handing out these awards, it was Swedish scientist Svante Papu 67 years Who won the prize? Nobel Prize in Medicine For his discoveries about human evolution, which revealed the secrets of Neanderthal DNA that helped understand what makes humans unique and provided new insights into our immune systems, including our exposure to the severe Covid virus.
