Conservation laws are central to our understanding of the universe, and now scientists have expanded our understanding of these laws in quantum mechanics.
Our current, well-established understanding of phases of matter primarily relates to systems that are at or near thermal equilibrium. However, there is a rich world of systems that are not in a state of equilibrium, which ...
Scientists at Linköping University have shown how a quantum computer really works and have managed to simulate quantum computer properties in a classical computer. "Our results should be highly significant in determining ...
