The QRNG uses a fluctuating quantum system to guarantee unpredictable randomness, which can be used in Web3 gaming and gambling. Researchers at Australia National University have teamed up with ...

Peter Bierhorst’s machine is no pinnacle of design. Nestled in the Rocky Mountains inside a facility for the National Institute of Standards and Technology, the photon-generating behemoth spans an ...

Imaginary numbers might seem like unicorns and goblins — interesting but irrelevant to reality. But for describing matter at its roots, imaginary numbers turn out to be essential. They seem to be ...

Several years ago one of us, Toni, asked another of us, Marco, to come to his office at the Institute of Photonic Sciences, a large research center in Castelldefels near Barcelona. “There is a problem ...

In quantum mechanics, measuring both the position and speed of a particle at the same time is not possible. To identify a particle's characteristics, physicists introduced the notion of ...
