Quantum computers also have some less savory uses. Given enough qubits, an algorithm invented by mathematician Peter Shor in 1994 could crack the encryption that underpins much of today’s internet.

That is changing how data centers — which are essentially big buildings filled with racks of computers stacked on top of one another — work. In 2021, before the A.I. boom, ...

But now, says Halimeh, quantum computers are slated to be “the major player” in understanding what happens in the hearts of particle colliders.
