In a citation many physicists expected for decades, this year’s Nobel Prize in Physics honors three researchers who probed a weird quantum mechanical phenomenon called entanglement, paving the way for the burgeoning fields of quantum communications and quantum computing. Two of them, John Clauser of J.F. Clauser & Associates and Alain Aspect of the University of Paris-Saclay and the Polytechnic Institute of Paris, proved quantum entanglement—which Albert Einstein derided as “spooky action at a distance”—cannot be explained by more intuitive classical physics. The third, Anton Zeilinger of the University of Vienna, showed how entanglement can be used to, for example, “teleport” information from one subatomic particle to another. The three share the 10 million Swedish kronor ($915,000) prize equally. “I’m absolutely thrilled,” says Adrian Kent, a quantum physicist at the University of Cambridge. “The recognition is overdue for these giants in the field.” Ronald Hanson, a quantum physicist at the Delft University of Technology, says, “It’s a beautiful prize.” The laureates’ work “has basically opened up this whole field of quantum information science and technologies,” he says. The tale of entanglement stretches back to 1935 and Einstein’s discontent with the contingent nature of quantum mechanics. Quantum theory states that the properties of an object such as an electron depend on how the thing is measured. Precisely measure the electron’s position and its momentum becomes u...

ANTON ZEILINGER is a physicist who has held teaching and research positions at M.I.T., the Universities of Innsbruck and Oxford, at the Technical Universities of Vienna and Munich, at the College de France in Paris. He us Professor of Physics at the Quantum Optics, Quantum Nanophysics, Quantum Information Institute of University of Vienna; and he is President of the Austrian Academy of Sciences. His work has received world-wide attention, most notably as a pioneer in the field of quantum information and of the foundations of quantum mechanics. In 2022, he won the Nobel Prize in Physics. He realized many important quantum information protocols for the first time, including quantum teleportation of an independent qubit, entanglement swapping (i.e. the teleportation of an entangled state), hyper-dense coding (which was the first entanglement-based protocol ever realized in experiment), entanglement-based quantum cryptography, one-way quantum computation and blind quantum computation. His further contributions to the experimental and conceptual foundations of quantum mechanics include multi-particle entanglement and matter wave interference all the way from neutrons via atoms to macromolecules such as fullerenes. He has written a number of articles on quantum physics for a general audience in journals like Scientific American, Nature, Science, Neue Zurcher Zeitung and Frankfurter Allgemeine Zeitung. He is the author of Dance of the Photons: From Einstein to Quantum Teleportati...

What happens to one of the particles in an entangled pair determines what happens to the other particle, even if they are far apart. In 1997–1998, Anton Zeilinger conducted groundbreaking experiments using entangled light particles, photons. These and other experiments confirm that quantum mechanics is correct and pave the way for quantum computers, quantum networks and quantum encrypted communication.

Clauser and Anton Zeilinger, today awarded the 2022 Nobel Prize in Physics. Aspect, Clauser and Zeilinger,were awarded this year’s prize“for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science.” Aspect, Optica Honorary Member and Professor at Université Paris-Saclay and École Polytechnique, Palaiseau, France, Clauser, Optica Emeritus Member andResearch Physicist atJ.F. Clauser & Assoc and Zeilinger, Optica Fellow and Professor at University of Vienna, Austria, are each awarded one-third of the prize. Their separate but related research employed practical experiments on entangled quantum states, laying the foundation for the emergence of quantum technology. “Drs. Aspect, Clauser, and Zeilinger established the quantum property of entanglement, and we celebrate the Nobel Foundation selection for their work in quantum optics,” remarked Satoshi Kawata, 2022 President of Optica and emeritus professor Osaka University, Japan. “Drs.

The physicists Alain Aspect, John Clauser and Anton Zeilinger have won the 2022 Nobel Prize in Physics for experiments that proved the profoundly strange quantum nature of reality. Their experiments collectively established the existence of a bizarre quantum phenomenon known as entanglement, where two widely separated particles appear to share information despite having no conceivable way of communicating. Entanglement lay at the heart of a fiery clash in the 1930s between physics titans Albert Einstein on the one hand and Niels Bohr and Erwin Schrödinger on the other about how the universe operates at a fundamental level. Einstein believed all aspects of reality should have a concrete and fully knowable existence. All objects — from the moon to a photon of light — should have precisely defined properties that can be discovered through measurement. Bohr, Schrödinger and other proponents of the nascent quantum mechanics, however, were finding that reality appeared to be fundamentally uncertain; a particle does not possess certain properties until the moment of measurement. Entanglement emerged as a decisive way to distinguish between these two possible versions of reality. The physicist John Bell “I would not call entanglement ‘one,’ but rather ‘the’ trait of quantum mechanics,” Thors Hans Hansson, a member of the Nobel committee, quoted Schrödinger as writing in 1935. He observed, “The experiments performed by Clauser and Aspect opened the eyes of the physics community to ...

Common sense is useless in the world of the extremely tiny, where the rules of quantum mechanics apply. One of the most amazing differences is that two particles —like two photons of light — Zeilinger, of the University of Vienna, Question. You first heard about quantum entanglement at a conference in 1976. What did you think? Answer. I didn’t understand what was going on. I just realized that it must be interesting. Q. How do you explain entanglement to people with no prior background in this field? A. No one is completely without prior background. The entanglement of two particles is like you have a pair of dice. Three is rolled on one die and three is also rolled on the other. If one die shows six, the other also shows six. And the same number always comes up on both dice. Q. Einstein said that God “does not play dice.” A. I believe that God puts the numbers so that we believe that he plays dice, but he does not play dice. God says: now it is three, now it is two, now it is six. And we believe that God plays dice. Q. In your Nobel lecture, you stated that “not even God” knows what information is in the particle. A. Maybe he knows. Or maybe not. We cannot know. Q. Do you use God as a metaphor or do you believe in God? A. Yes. Why not believe? The famous Isaac Newton published books on many subjects, but he wrote much more about religion than physics. He was a religious person. Q. Two entangled particles can be imagined as twin brothers who behave similarly at a distance ...

Experiments on a bizarre feature of quantum physics known as entanglement (illustrated here as two objects entangled into one) have netted the 2022 Nobel Prize in physics. When two particles are entangled, what happens to one determines what happens to the other — even if the particles are far apart. Nicolle R. Fuller/NSF Tests of quantum weirdness and its potential real-world applications have been recognized with the 2022 Nobel Prize in physics. At some level we are all subject to quantum rules that even Albert Einstein struggled to come to terms with. For the most part, these rules play out behind the scenes in transistors that make up computer chips, lasers and even in the chemistry of atoms and molecules in materials all around us. Applications that stem from this year’s Nobel Prize take advantage of quantum features at larger scales. They include absolutely secure communications and quantum computers that may eventually solve problems that no conceivable conventional computer could complete in the lifetime of the universe. This year’s prize is shared among three physicists. Alain Aspect and John Clauser confirmed that the rules of quantum mechanics, as weird and difficult to believe as they are, really do rule the world, while Anton Zeilinger has taken advantage of strange quantum behavior to develop rudimentary applications that no conventional technology can match. Each laureate will take home a third of the prize money, which totals 10 million Swedish kronor, wort...
