Understanding the structure of correlations within our current description of nature, based on quantum physics, is a fundamental open problem. In particular, one would like to characterize the set of ...
Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...
In the early 1920s, physicists were first working out the mysteries of the quantum Universe. Particles sometimes behaved as waves, with indeterminate positions, momenta, energies, and other properties ...
