Wormhole Experiment Called Into Question
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
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
The quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works.
The Year in Computer Science
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
The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.
New Entanglement Results Hint at Better Quantum Codes
A team of physicists has entangled three photons over a considerable distance, which could lead to more powerful quantum cryptography.
Pioneering Quantum Physicists Win Nobel Prize in Physics
Alain Aspect, John Clauser and Anton Zeilinger have won the 2022 Nobel Prize in Physics for groundbreaking experiments with entangled particles.
Computer Science Proof Unveils Unexpected Form of Entanglement
Three computer scientists have posted a proof of the NLTS conjecture, showing that systems of entangled particles can remain difficult to analyze even away from extremes.
Cryptographers Achieve Perfect Secrecy With Imperfect Devices
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.
