Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that ...

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

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 ...

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 ...

Researchers demonstrate that some forms of quantum behavior can only occur via pairwise interactions, a finding that limits the number of ways in which we can reconcile quantum mechanics with ...

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