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

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 ...

I’ve dedicated over 20 years of my life to the study of noisy quantum systems, as a Professor, and I never thought this type of experiment would be possible so soon. Needless to say, I’m extremely ...

A new experiment could in principle test the quantumness of an object regardless of its mass or energy. An experiment outlined by a UCL (University College London)-led team of scientists from the UK ...

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?

An experiment outlined by a UCL-led team could test whether relatively large masses have a quantum nature, resolving the question of whether quantum mechanical description works at a much larger scale ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...
