Physicists have developed the first conclusive test to better understand high-energy particles correlations. Researchers have devised a proposal for the first conclusive experimental test of a phenomenon known as ℠Bell´s nonlocality.´ This test is designed to reveal correlations that are stronger than any classical correlations, and do so between high-energy particles that do not consist of ordinary matter and light. These results are relevant to the so-called ℠CP...

Researchers have devised a new kind of random number generator, for encrypted communications and other uses, that is cryptographically secure, inherently private and "“ most importantly "“ certified random by laws of physics. That is important because randomness is surprisingly rare. Although the welter of events that transpire in the course of daily life can certainly seem haphazard and arbitrary, none of them is genuinely random in the sense that they could not be predicted...

Researchers at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (NIST/University of Maryland) have developed a new method for creating pairs of entangled photons, particles of light whose properties are interlinked in a very unusual way dictated by the rules of quantum physics. The researchers used the photons to test fundamental concepts in quantum theory.In the experiment, the researchers send a pulse of light into both ends of a twisted loop of...
