Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

Physicists confirm that light has two identities that are impossible to see at once. (Nanowerk News) MIT physicists have performed an idealized version of one of the most famous experiments in quantum ...

If quantum weirdness is all in the mind, what about optical interference? Set up apparatus that can record the arrival of an individual photon on a screen after passing through one of two slits, and ...
