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

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

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

In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

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 ...

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 ...

A team of scientists recently conducted an exciting quantum physics experiment allowing them to demonstrate that reality might actually be real. Well, don’t everybody applaud all at once. It’s ...

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 ...
