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.

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

Several weeks ago I picked up “The Elegant Universe” because I thought it would have information on The Ultimate Theory. Soon afterwards, I picked up “How to Teach Physics To Your Dog” in order to get ...

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

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

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

A photon was apparently detected in two places at once in a twist on the classic double-slit experiment, but many physicists ...

It's time for the latest update in confirming things we already knew—and, as always, it's being far more interesting than you might expect. Simply put, scientists have conducted a super-advanced ...

Physicists confirm that light has two identities that are impossible to see at once. (Nanowerk News) MIT physicists have performed an idealized version of one of the most famous experiments in quantum ...

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 ...

I just want to say that this should have been obvious, but it really helps to explain why you only see point excitations when the photon is a wave. That part was really bothering me. I'm just a ...
