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

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

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

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 ...

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

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 ...

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 ...

God does not play dice with the universe,” Albert Einstein famously declared in 1927, sparking one of the most enduring ...

Back in the 1920s, quantum mechanics, which is the theory that underpins everything from how atoms behave to how quantum computers work, was well on the way to gaining mainstream acceptance. But one ...
