Quantum leap in lasers brightens future of quantum computing
Hanover NH (SPX) Jul 24, 2014
Dartmouth scientists and their colleagues have devised a breakthrough laser that uses a single artificial atom to generate and emit particles of light. The laser may play a crucial role in the development of quantum computers, which are predicted to eventually outperform today's most powerful supercomputers. The study appears in the journal Physical Review B. The new laser is the first to rely exclusively on superconducting electron pairs. "The fact that we use only superconducting pairs is ... read more
