Freezing single atoms to near absolute zero with microwaves brings practical quantum technology closer
July 2, 2015
Physicists at the University of Sussex have frozen single ytterbium ions (charged atoms) to within a millionth of a degree of absolute zero (minus 273.15°C), using 12.6 GHz microwave radiation combined with a large static magnetic field gradient. Temperatures near absolute zero are required to hold ions stationary for quantum computing and other applications.
The physicists measured a reduction of almost two orders of magnitude in the… read more
