Quantum interference involving three photons has been measured by two independent teams of physicists. Seeing the effect requires the ability to deliver three indistinguishable photons to the same ...

Researchers demonstrate that some forms of quantum behavior can only occur via pairwise interactions, a finding that limits the number of ways in which we can reconcile quantum mechanics with ...

A simple experiment that sends photons through three slits provides the best proof yet of an important axiom of quantum theory called Born’s rule, say physicists in Canada and Austria. The ...

I think what I read was saying that in quantum mechanics, when more than two possibilities are present, the other possibilities are ignored by the particles. And that in terms of the experiment, when ...
