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 ...

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

"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 ...

A persistent group of scientists at the University of Warsaw have accomplished the impossible by creating a hologram of a solitary particle of light, reports Business Insider.

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

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 ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

The quantum photonic chip used to test wave-particle duality in the Bristol experiment. Single photons are sent into the circuit using optical fibers, and are detected at the output using extremely ...
