Record-breaking number of qubits entangled in a quantum computer
12 July 2023
A group of 51 superconducting qubits have been entangled inside a quantum computer, not just in pairs but in a complex system that entangles each qubit to every other one

Microsoft says its weird new particle could improve quantum computers
21 June 2023
Researchers at Microsoft say they have created elusive quasiparticles called Majorana zero modes – but scientists outside the company are sceptical
IBM quantum computer beat a supercomputer in a head-to-head test
14 June 2023
Researchers at IBM pitted their 127-qubit Eagle quantum computer against a conventional supercomputer in a challenge to perform a complex calculation – and the quantum computer won
A miniature universe shows particles may emerge out of empty space
9 November 2022
A first-of-its-kind experiment simulating the cosmos with ultracold potassium atoms suggests that in a curved, expanding universe pairs of particles pop up out of empty space
Carlo Rovelli interview: "Reality is not things, but connections"
13 October 2022
Inspired by the art of Cornelia Parker, physicist Carlo Rovelli explains the idea of relational quantum mechanics - and how it could resolve some key problems concerning the nature of reality.
Nobel prize in physics awarded to pioneers of quantum information

The 2022 Nobel prize in physics has been jointly awarded to Alain Aspect, John F. Clauser and Anton Zeilinger
Can we build a quantum clock that is entirely quantum?
5 August 2022
Quantum clocks are normally controlled by a classical control system, but to build things like tiny quantum drones that fly around delivering molecules we'll need a fully quantum approach
Quantum computer can simulate infinitely many chaotic particles
4 August 2022
Using just a handful of quantum bits, researchers have used a quantum computer to simulate an infinite line of electron-like particles. The technique could be used to better understand the behaviour of molecules in materials
Physicists have made a quantum boomerang for the first time
11 June 2022
Hundreds of thousands of lithium atoms cooled to near absolute zero exhibit a strange quantum effect a bit like a boomerang
Quantum communication system could detect earthquakes
17 May 2022
Quantum-encrypted messages sent through cables over long distances are sensitive to tiny vibrations, suggesting a possible by-product of a future secure network
