Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that ...

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new subbasement with even weirder stuff. The number one hater of thi ...

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

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

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 ...

The classic double-slit experiment of quantum physics involves shining light through two narrow gaps to show that it can behave as a wave – now it seems the slits can be entirely replaced by a single ...
