Serge Haroche, a French-Jewish physicist, has won the Nobel Prize in Physics jointly with David Wineland from the United States.
The 2012 prize went to the scientists “for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems,” the website of the Nobel Prize said.
According to the BBC, the pair developed solutions to pick, manipulate and measure photons and ions individually, allowing an insight into a microscopic world that was once just the province of scientific theory.
Haroche, who was born 68 years ago in Casablanca, Morocco, told Le Figaro that he “had a hard time understanding” the news when a representative of the Nobel Prize committee called him on his cellular phone to say he had won what is considered the highest form of recognition of scientific excellence.
Haroche, of Collège de France and Ecole Normale Supérieure, will share a $1.2 million grant from the Nobel Prize Committee with Wineland, a researcher at the Maryland-based National Institute of Standards and Technology and at the University of Colorado.
Haroche gave a series of lectures on quantum physics at the Technion last year.
Le Figaro quoted him saying he was walking with his wife down the street when he received the call from Sweden. He said he had to sit down on a bench before passing on the news to family.
Richard Prasquier, the president of CRIF, the umbrella organization of France’s Jewish communities, told JTA: “The achievement belongs to the scientists, but a small part of me is also proud today.” Mutual friends described Haroche to Prasquier as “a truly brilliant thinker, known for his creativity,” Prasquier said.
Prasquier noted that Haroche had worked closely with Claude Cohen-Tannoudji – also a French Jew of North African descent – who won the Nobel Prize in physics in 1997.
The Algeria-born Cohen-Tannoudji, 79, is still an active researcher at Ecole Normale Supérieure in Paris.
Haroche and Wineland invented methods to observe the bizarre properties of the quantum world — research that has led to the construction of extremely precise clocks and helped scientists take the first steps toward building superfast computers.
Experts say the duo opened the door to new experiments in quantum physics by showing how to observe individual quantum particles while preserving their quantum properties. A quantum particle is one that is isolated from everything else. In this situation, an atom or electron or photon takes on strange properties. It can be in two places at once, for example. It behaves in some ways like a wave. But these properties are instantly changed when it interacts with something else, such as when somebody observes it.
Working separately, the two scientists, both 68, developed “ingenious laboratory methods” that allowed them to manage and measure and control fragile quantum states, the Royal Swedish Academy of Sciences said.
“Their ground-breaking methods have enabled this field of research to take the very first steps towards building a new type of superfast computer based on quantum physics,” the academy said. “The research has also led to the construction of extremely precise clocks that could become the future basis for a new standard of time.”
The two researchers use opposite approaches to examine, control and count quantum particles, the academy said.
Wineland traps ions — electrically charged atoms — and measures them with light, while Haroche controls and measures photons, or light particles.
“I was in the street [when he got the news] and passing a bench so I was able to sit down,” Haroche told a news conference in Stockholm by telephone. “It’s very overwhelming.”
He said his work in the realm of quantum physics could ultimately lead to unimaginably fast computers.
“You can do things which are prohibited by the laws of classical physics,” he said.
Haroche also said quantum research could help make GPS navigating systems more accurate.
NIST spokesman Jim Burrus said Wineland was asleep at home in Boulder when the call came in early Tuesday notifying him that he won; his wife answered the phone. Burrus said Wineland described the news as overwhelming and wonderful.
He described Wineland as a humble person who never expected to win prizes. He also doesn’t take himself very seriously: Wineland once played first base on a NIST softball team called “Field of Dweebs.”
Christopher Monroe, who does similar work at the Joint Quantum Institute at the University of Maryland, said the awarding of the prize to the two men “is not a big surprise to me … It was sort of obvious that they were a package.”
Monroe said that thanks to the bizarre properties of the quantum world, when he and Wineland worked together in the 1990s, they were able to put a single atom in two places simultaneously.
At that time, it wasn’t clear that trapping single atoms could help pave the way to superfast quantum computers, he said. That whole field “just fell into our laps,’” Monroe said.
In an ordinary computer, information is represented in bits, each of which is either a zero or a one. But in a quantum computer, an individual particle can essentially represent a zero and a one at the same time. If scientists can make such particles work together, certain kinds of calculations could be done with blazing speed.
One example is the factoring, the process of discovering what numbers can be multiplied together to produce a given number. That has implications for breaking codes, Monroe said.
Quantum computers could radically change people’s lives in the way that classical computers did last century, but a full-scale quantum computer is still decades away, the Nobel judges said.
“The calculations would be incredibly much faster and exact and you would be able to use it for areas like metrology and for measuring the climate of the earth,” said Lars Bergstrom, the secretary of the prize committee.
The physics prize was the second of the 2012 Nobel Prizes to be announced, with the medicine award going Monday to stem cell pioneers John Gurdon of Britain and Japan’s Shinya Yamanaka. Each award is worth 8 million kronor, or about $1.2 million.
Only two women have won the physics prize since it was first awarded in 1901: Marie Curie in 1903 and Maria Goeppert-Mayer in 1963.
The prizes are always handed out on Dec. 10, the anniversary of prize founder Alfred Nobel’s death in 1896.
