Upcoming experimental tests of gravity’s quantumness aim to resolve one of the biggest questions in physics, but theorists ...

Does anyone understand quantum theory? The legendary Richard Feynman suggested that if you think you do, you haven’t understood it at all. But quantum theory is our best description of the microscopic ...

Quantum researchers in the twenty-first century are part of an international network that requires a great deal of ...

Natalie Paquette spends her time thinking about how to grow an extra dimension. Start with little circles, scattered across every point in space and time—a curlicue dimension, looped back onto itself.

The firm says it has solved a problem on a quantum processor faster than a classical computer, and is optimistic about future ...

Michel Devoret and John Martinis win award In simple terms, their work showed that when electric circuits are made extremely small and cooled to near absolute zero, they start behaving like atoms — ...
