Preserving coherence keeps quantum systems clear and comprehensible. We say a message is incoherent when we can’t make it out, or when it doesn’t make sense. A scribbled note, a drunken argument or a ...

Quantum computers promise to lead to major advances in certain areas of complex computing. One of the roadblocks to achieving such dream computers, however, is the fact that quantum phenomena, which ...

Physicists are rapidly expanding the traditional menu of matter beyond solids, liquids, gases and plasmas, uncovering exotic phases that behave in ways no classroom diagram ever captured. In the ...

Microcavity exciton–polaritons are quantum oscillation states formed under strong coupling between microcavity photons and semiconductor excitons. As bosonic quasiparticles with a “half-light, ...
