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.

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

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

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

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 ...

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

We’ve all seen recreations of the famous double-slit experiment, which showed that light can behave both as a wave and as a particle. Or rather, it’s likely that what we’ve seen is the results of the ...

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 ...
