French, Serge Haroche and American, David Wineland win Nobel prize in physics

Tuesday, 09 October 2012
The Royal Swedish Academy of Sciences has this awarded the 2012 Nobel prize in physics to two researchers for their work with the fundamental units of light.

They are Serge Haroche, from Collège de France and Ecole Normale Supérieure, Paris, France and David J. Wineland National Institute of Standards and Technology (NIST) and University of Colorado Boulder, CO, USA, the Royal Institute said in a press release on Tuesday.

The award is "for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems"

According to the award institute, Serge Haroche and David J. Wineland have independently invented and developed methods for measuring and manipulating individual particles while preserving their quantum-mechanical nature, in ways that were previously thought unattainable.

The Nobel Laureates have opened the door to a new era of experimentation with quantum physics by demonstrating the direct observation of individual quantum particles without destroying them. For single particles of light or matter, the laws of classical physics cease to apply and quantum physics takes over.

But single particles are not easily isolated from their surrounding environment and they lose their mysterious quantum properties as soon as they interact with the outside world. Thus, many seemingly bizarre phenomena predicted by quantum physics could not be directly observed, and researchers could only carry out thought experiments that might in principle manifest these bizarre phenomena.
