The Nobel Prize in Physics was awarded to Alain Aspect, John F. Clauser and Anton Zeilinger on Tuesday for work that has “laid the foundation for a new era of quantum technology,” the Nobel Committee for Physics said.
The scientists have each conducted “groundbreaking experiments using entangled quantum states, where two particles behave like a single unit even when they are separated,” the committee said in a briefing. Their results, it said, cleared the way for “new technology based upon quantum information.”
The laureates’ research builds on the work of John Stewart Bell, a physicist who strove to address the question of whether particles, having flown too far apart for there to be normal communication between them, can still function in concert.
Eva Olsson, a member of the Nobel Committee for Physics, noted that quantum information science had broad implications in areas like secure information transfer and quantum computing.
Quantum information science is a “vibrant and rapidly developing field,” she said. “Its predictions have opened doors to another world, and it has also shaken the very foundation of how we interpret measurements.”
The Nobel committee said the three scientists were being honored for their experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science.
“Being able to manipulate and manage quantum states and all their layers of properties gives us access to tools with unexpected potential,” the committee said in a statement on Twitter.
Dr. Zeilinger described the award as “an encouragement to young people.”
“The prize would not be possible without more than 100 young people who worked with me over the years and made all this possible,” he said.
Though he acknowledged that the award was recognizing the future applications of his work, he said, “My advice would be: Do what you find interesting, and don’t care too much about possible applications.”
It was the second of several such prizes to be awarded over the coming week. The Nobels, among the highest honors in science, recognize groundbreaking contributions in a variety of fields.
“I’m still kind of shocked, but it’s a very positive shock,” Dr. Zeilinger said of receiving the phone call informing him of the news.
Who won the Nobel Prize in Physics in 2021?
The prize was awarded to Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi for their work detailing humanity’s role in climate change.
Who else has won a Nobel Prize in the sciences this year?
The Physiology or Medicine prize was awarded on Monday to Svante Pääbo, a Swedish scientist who peered back into human history by retrieving genetic material from 40,000-year-old bones, producing a complete Neanderthal genome and initiating the field of ancient DNA studies.
When will the other Nobel Prizes be announced?
The Nobel Prize in Chemistry will be awarded on Wednesday by the Royal Swedish Academy of Sciences in Stockholm. Last year, Benjamin List and David W.C. MacMillan won for their development of a new tool that spurred research into new drugs and reduced the chemistry’s effect on the environment.
The Nobel Prize in Literature will be awarded on Thursday by the Swedish Academy in Stockholm. Last year, Abdulrazak Gurnah won for “his uncompromising and compassionate penetration of the effects of colonialism and the fate of the refugee in the gulf between cultures and continents.”
The Nobel Peace Prize will be awarded on Friday by the Norwegian Nobel Institute in Oslo. Last year, Maria Ressa and Dmitri A. Muratov, both journalists, won for their efforts in the struggle to protect press freedoms.
Next week, the Nobel Memorial Prize in Economic Sciences will be awarded on Monday by the Swedish Academy in Stockholm. Last year, the prize went to David Card, Joshua D. Angrist and Guido W. Imbens.
All of the prize announcements will also be streamed live by the Nobel Prize organization. Prize winners will receive their awards at a ceremony in Stockholm in December.
