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

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

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

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 ...

The double-slit connection In their paper, the authors draw an elegant analogy to the famous double-slit experiment, where particles like electrons produce interference patterns when passed through ...
