entanglement

For the first time, experiments demonstrate the possibility of sharing secrets with perfect privacy — even when the devices used to share them cannot be trusted.

For over two decades, physicists have pondered how the fabric of space-time may emerge from some kind of quantum entanglement. In Monika Schleier-Smith’s lab at Stanford University, the thought experiment is becoming real.

In a landmark series of calculations, physicists have proved that black holes can shed information.

Can we test speculations about how quantum physics affects black holes and the Big Bang?

Computer scientists established a new boundary on computationally verifiable knowledge. In doing so, they solved major open problems in quantum mechanics and pure mathematics.

A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.

Pure, verifiable randomness is hard to come by. Two proposals show how to make quantum computers into randomness factories.

The universe of problems that a computer can check has grown. The researchers’ secret ingredient? Quantum entanglement.

These games combine quantum entanglement, infinity and impossible-to-calculate winning probabilities. But if researchers can crack them, they’ll reveal deep mathematical secrets.
