Researchers successfully demonstrate a quantum gate in silicon

Milestone on the path to the quantum computer: Scientists of the University of Konstanz, Princeton University, and the University of Maryland have developed a stable quantum gate for two-quantum bit systems made of silicon. The quantum gate is able to perform all necessary basic operations of the quantum computer. The electron spin of individual electrons in silicon is used as the basic storage unit ("quantum bits"). The research results were published ahead of print in Science on 7 December 201...
