Physicists get thousands of semiconductor nuclei to do 'quantum dances' in unison

EurekAlert   -   Scientific News Websites

The Cambridge team found a way to exploit the interaction between the electron and the thousands of nuclei using lasers to 'cool' the nuclei to less than 1 milliKelvin. They then showed they can control and manipulate the thousands of nu...
