The Electron Is So Round That It’s Ruling Out Potential New Particles

April 10, 2023

If the electron’s charge wasn’t perfectly round, it could reveal the existence of hidden particles. A new measurement approaches perfection.

How to Tame the Endless Infinities Hiding in the Heart of Particle Physics

April 6, 2023

In the math of particle physics, every calculation should result in infinity. The set of techniques known as “resurgence” points toward an escape.

Wormhole Experiment Called Into Question

March 23, 2023

Last fall, a team of physicists announced that they had teleported a qubit through a holographic wormhole in a quantum computer. Now another group suggests that’s not quite what happened.

Black Holes Will Eventually Destroy All Quantum States, Researchers Argue

March 7, 2023

New calculations suggest that the event horizons around black holes will ‘decohere’ quantum possibilities — even those that are far away.

Physicists Use Quantum Mechanics to Pull Energy out of Nothing

February 22, 2023

The quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works.

How Our Reality May Be a Sum of All Possible Realities

February 6, 2023

Richard Feynman’s path integral is both a powerful prediction machine and a philosophy about how the world is. But physicists are still struggling to figure out how to use it, and what it means.

How Quantum Physicists ‘Flipped Time’ (and How They Didn’t)

January 27, 2023

Two teams have made photons act as if time were simultaneously flowing in two directions. The experiments demonstrate a way to potentially boost the performance of quantum devices.

The Year in Computer Science

December 21, 2022

Computer scientists this year learned how to transmit perfect secrets, why transformers seem so good at everything, and how to improve on decades-old algorithms (with a little help from AI).

Physicists Create a Holographic Wormhole Using a Quantum Computer

November 30, 2022

The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.
