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

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

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

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

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 ...

The double-slit experiment is the most famous and probably the most important experiment in quantum physics: individual particles are shot at a wall with two openings, behind which a detector measures ...
