This year’s Nobel Prize in Physics goes to three scientists who specialize in quantum mechanics, the science that describes the behavior of subatomic particles. That is, physics on the smallest possible scale.
Frenchman Alain Aspect, American star John Klosser and Austrian Anton Seilinger received the prize.
His work will pave the way for a new generation Powerful computers and telecommunication systems Impossible to hack.
This year’s three laureates conducted innovative experiments using entangled quantum states, where two subatomic particles act as a single unit even if separated.
“Quantum Information Science A.” Energetic field and developing rapidly,” said Eva Olsson, a member of the Nobel Committee for Physics. Broad and potential implications in areas such as secure information exchange, quantum computing and sensing technology.”
Quantum mechanics describes the behavior of subatomic particles. This is a field of research that started in the early 20th century.
“Entanglement” is an area of quantum mechanics in which two or more quantum particles – usually photons, particles of light – become strongly associated when they are far apart. without physical contact.
Your shared state can be your energy or your spin. It’s a strange phenomenon that Albert Einstein called “spooky action at a distance.”
The theoretical foundation was developed in the 1960s by Northern Irish physicist John Stuart Bell. But the experiments were done by Aspect, Closer and Seilinger showOn that the phenomenon is real And there may be practical uses.
“From the first moment I read about quantum mechanics, I was always interested in it,” Zeilinger told the BBC.
“I was very impressed by some of the theoretical predictions, because Not suitable for ordinary intuitions One can get that,” Vijayi pointed out.
Entanglement research has received much attention in two areas. One of them is quantum computers, which promise a huge leap in the ability of machines to solve them. Complex problems.
Another is cryptography, the secure encoding of information that makes it impossible for a third party to intercept private communications.
“It’s useful Army and Banks Etc. in secure communications,” Clauser said.
“The biggest application I know of is from the Chinese, who launched a satellite several years ago that they use for secure communications over thousands of miles,” he added.
Professor Tim Spiller, of the University of York in the UK, said Tuesday’s laureates were worthy winners and helped open up an exciting future.
“Quantum technologies have been heavily researched in the UK and many other countries over the last 10 years. We’ve known about this mess for a long time, but there’s been investment in the last 10 years. Now there’s one or two. Buyable products that use different aspects of this quantum feature are emerging, we hope. Many more to come“, he claimed.
