A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

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 ...

Albert Einstein was right about a shocking among of things, but not necessarily everything.

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 ...

Most of us have heard about the double-slit experiment being performed using photons or electrons, but what about atoms and molecules? Prepare to have your mind boggled! Most of us have heard about ...

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 ...
