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 ...

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

Researchers have finally resolved a century-old debate over the famous "double slit" experiment, according to new research.

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 ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

A photon was apparently detected in two places at once in a twist on the classic double-slit experiment, but many physicists ...
