University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

Atsushi Sakaguchi and his team are exploring the possibility of using light to produce quantum computers that are measurement based rather than gate based. Credit: RIKEN Atsushi Sakaguchi and his team ...

Quantum experiments keep stripping away our everyday intuitions, replacing them with a picture of reality in which cause, effect and even “facts” depend on how we look. New tests of entanglement, ...

A 91-qubit superconducting processor manages to simulate quantum chaos with unprecedented precision despite experimental ...

Imagine a physicist observing a quantum system whose behavior is akin to a coin toss: it could come up heads or tails. They perform the quantum coin toss and see heads. Could they be certain that ...
