Calculating the benefits of exascale and quantum computers

A quintillion calculations a second. That's one with 18 zeros after it. It's the speed at which an exascale supercomputer will process information. The Department of Energy (DOE) is preparing for the first exascale computer ...

Quantum simulators for gauge theories

To simulate in a laboratory what happens in particle accelerators has been an ambitious goal in the study of the fundamental forces of nature pursued by high-energy physicists for many years. Now, thanks to research conducted ...

Quantum gases won't take the heat

The quantum world blatantly defies intuitions that we've developed while living among relatively large things, like cars, pennies and dust motes. In the quantum world, tiny particles can maintain a special connection over ...

Peeking into a world of spin-3/2 materials

Researchers have been pushing the frontiers of the quantum world for over a century. And time after time, spin has been a rich source of new physics.

Novel quantum effect found: Spin-rotation coupling

Imagine a dancer en pointe, spinning on her own axis while dancing on a rotating carousel. She might injure herself when both rotations add up and the angular momentum is transferred. Are similar phenomena also present in ...

Unexpected twist in a quantum system

Physicists at ETH Zurich have observed a surprising twist in a quantum system caused by the interplay between energy dissipation and coherent quantum dynamics. To explain it, they found a concrete analogy to mechanics.
