An “echo” that arrives before you finish speaking sounds like a glitch. In quantum hardware, that kind of self-interference ...

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

Quantum computers need special materials called topological superconductors—but they’ve been notoriously difficult to create. Researchers have now shown they can trigger this exotic state by subtly ...

New evidence suggests a rare triplet superconductor may help quantum computers stay in sync by preserving electron spin ...

In a lab in Hangzhou, China, a small chip may have just passed one of the most difficult honesty tests in physics. The test wasn’t about lying in the human sense, but about proving that it really is ...

Quantum chaos used to be the kind of phrase that made experimental physicists wince, a shorthand for fragile devices going off the rails when too many particles started talking to each other. Now a ...
