Bay Area physicist, 2 others share Nobel Prize for work on quantum science

By DAVID KEYTON and FRANK JORDANS | The Related Press

STOCKHOLM — Three scientists collectively gained this 12 months’s Nobel Prize in physics on Tuesday for his or her work on quantum info science that has important purposes, for instance within the discipline of encryption.

Frenchman Alain Side, American John F. Clauser and Austrian Anton Zeilinger had been cited by the Royal Swedish Academy of Sciences for locating the best way that unseen particles, corresponding to photons or tiny bits of matter, will be linked, or “entangled,” with one another even when they're separated by giant distances.

“Being somewhat bit entangled is type of like being somewhat bit pregnant. The impact grows on you,” Clauser mentioned in a Tuesday morning cellphone interview with The Related Press.

All of it goes again to a function of the universe that even baffled Albert Einstein and connects matter and light-weight in a tangled, chaotic manner.

Clauser, 79, was awarded his prize for a 1972 experiment that helped settle a well-known debate about quantum mechanics between Einstein and famed physicist Niels Bohr. Einstein described “a spooky motion at a distance” that he thought would ultimately be disproved.

“I used to be betting on Einstein,” Clauser mentioned. “However sadly I used to be fallacious and Einstein was fallacious and Bohr was proper.”

Clauser, who from 1969 to 1996 labored at Lawrence Berkeley Nationwide Laboratory, Lawrence Livermore Nationwide Laboratory, and the College of California, Berkeley, mentioned his work on quantum mechanics exhibits which you can’t confine info to a closed quantity, “like somewhat field that sits in your desk” — although even he can’t say why.

“Most individuals would assume that nature is made out of stuff distributed all through area and time,” Clauser mentioned. “And that seems to not be the case.”

Quantum entanglement “has to do with taking these two photons after which measuring one over right here and understanding instantly one thing concerning the different one over right here,” mentioned David Haviland, chair of the Nobel Committee for Physics. “And if now we have this property of entanglement between the 2 photons, we will set up a typical info between two totally different observers of those quantum objects. And this permits us to do issues like secret communication, in methods which weren’t doable to do earlier than.”

That’s why quantum info isn't an esoteric thought experiment, mentioned Eva Olsson, a member of the Nobel committee. She known as it a “vibrant and creating discipline.”

“It has broad and potential implications in areas corresponding to safe info switch, quantum computing and sensing expertise,” Olsson mentioned. “Its predictions have opened doorways to a different world, and it has additionally shaken the very foundations of how we interpret measurements.”

Every part within the universe might be entangled however “normally the entanglement simply sort of washes off. It’s so chaotic and random that once you have a look at it … we don’t see something,” mentioned Harvard professor Subir Sachdev, who has labored on experiments that have a look at quantum entangled materials consisting of as much as 200 atoms. However typically scientists can unsnarl simply sufficient to make sense and be helpful in all the things from encryption to superconductors, he mentioned.

Talking by cellphone to a information convention after the announcement, Zeilinger mentioned he was “nonetheless sort of shocked” at listening to he had obtained the award.

“But it surely’s a really constructive shock,” mentioned Zeilinger, 77, who is predicated on the College of Vienna.

Clauser, Side, and Zeilinger have figured in Nobel hypothesis for greater than a decade. In 2010 they gained the Wolf Prize in Israel, seen as a doable precursor to the Nobel.

Whereas physicists usually sort out issues that seem at first look to be far faraway from on a regular basis considerations — tiny particles and the huge mysteries of area and time — their analysis supplies the foundations for a lot of sensible purposes of science.

The Nobel committee mentioned Clauser developed quantum theories first put ahead within the Sixties right into a sensible experiment. Side, 75, was capable of shut a loophole in these theories, whereas Zeilinger demonstrated a phenomenon known as quantum teleportation that successfully permits info to be transmitted over distances.

“Utilizing entanglement you may switch all the knowledge which is carried by an object over to another place the place the item is, so to talk, reconstituted,” mentioned Zeilinger. He added that this solely works for tiny particles.

“It isn't like within the Star Trek movies (the place one is) transporting one thing, actually not the particular person, over far,” he mentioned.

When he started his analysis, Zeilinger mentioned the experiments had been “utterly philosophical with none doable use or utility.”

Since then, the laureates’ work has been used to develop the fields of quantum computer systems, quantum networks and safe quantum encrypted communication.

Per week of Nobel Prize bulletins kicked off Monday with Swedish scientist Svante Paabo receiving the award in medication Monday for unlocking secrets and techniques of Neanderthal DNA that supplied key insights into our immune system.

They proceed with chemistry on Wednesday and literature on Thursday. The 2022 Nobel Peace Prize will probably be introduced on Friday and the economics award on Oct. 10.

The prizes carry a money award of 10 million Swedish kronor (almost $900,000) and will probably be handed out on Dec. 10. The cash comes from a bequest left by the prize’s creator, Swedish inventor Alfred Nobel, who died in 1895.
