Bell’s theorem states that quantum mechanics is incompatible with local realism. He showed that if we assume, in line with Einstein’s theory of relativity, that ther ...

This hypothesis is corroborated if direct detection yields no clicks at all; otherwise an occurrence of a click unambiguously identifies the location of the pulse in one of the directly detected ...
