Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

Researchers use an updated version of slit experiment, and figure out who was correct between Einstein and Bohrs regarding ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

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

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

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

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 ...
