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.

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

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

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

Scientists observe unusual interference phenomena by scattering laser light from two atoms trapped inside an optical resonator. MPQ scientists observe unusual interference phenomena by scattering ...

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

(Inside Science) — One of the strangest things about quantum mechanics is that a particle can act like a wave. In particular, in a double-slit experiment, individual particles that are shot through a ...

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 ...

An international group of physicists has found a way of measuring both the position and the momentum of photons passing through the double-slit experiment, upending the idea that it is impossible to ...
