Frenchman Serge Haroche of the College de France and Ecole Normale Superieure, Paris, and American David Wineland of the University of Colorado in Boulder.
The two were cited for inventing and developing methods for observing tiny quantum particles without destroying them.
Their research has led to the construction of extremely precise clocks that could become the basis for a new standard of measuring time and helped scientists take the first steps toward building superfast computers.
WHAT THEY SAID?
Haroche: "It's very overwhelming. ... At first I called my children. ... There are a lot of people in the world that deserve the prize so I tried to not to expect too much." Wineland: "It was certainly surprising, and kind of overwhelming right now...I feel like I got a lot smarter overnight. ... When they also told me that the prize was shared with a good friend, that was nice to hear, too."
