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 ...

MIT physicists have recreated the most iconic experiment in quantum physics — this time with individual atoms acting as the slits and single photons barely grazing past. Their results have firmly ...

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

A team of physicists has reimagined one of science’s most iconic experiments—but in the dimension of time. Researchers at Imperial College London have taken the classic double-slit test and turned it ...

(via Sabine Hossenfelder) The double-slit experiment is a famous quantum physics experiment that shows that light exhibits behavior of both a particle and a wave. In a new paper, researchers claim ...

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, ...

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 ...
