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

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

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

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...

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