"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 ...

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

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

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

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

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 precise methodology of Richard Feynman's famous double-slit thought-experiment – a cornerstone of quantum mechanics that showed how electrons behave as both a particle and a wave – has been ...
