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

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

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

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By ...

In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of ...

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...
