Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped for.

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to disprove the quantum mechanical principle of complementarity put forth by ...

A physics experiment published this year that claimed to measure a single photon in two places at once – and, in the process, discredit the idea of a multiverse – drew pushback from many sceptical ...
