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?

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

Record-breaking experiment shows that a cluster of thousands of atoms can act like a wave as well as a particle.

John Martinis has already revolutionised quantum computing twice. Now, he is working on another radical rethink of the ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...
