Quantum computers prove their superiority over classical machines in new game
For decades, physicists have worked to prove the strange predictions of quantum mechanics with real experiments. As quantum computers have grown more powerful, researchers have devised increasingly…
Superfluid qubit could help scale up quantum computers
Superfluid helium could offer a new way to tackle one of the biggest challenges in scaling up quantum computers, say researchers from the University of Surrey. The research team has introduced a…
Scientists observe Einstein’s gravity in the quantum world for the first time
Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to a striking new test. Using ultracold atoms, researchers split an…
The danger of viewing the cosmos as a mirror that shows us ourselves
It is only natural to view the world, or even the entire universe, through the lens of humanity – we’re human, after all. But columnist Chanda Prescod-Weinstein says we can appreciate the wonder…
