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

Google's quantum supremacy challenged by ordinary computers, for now
18 August 2022
In 2019, Google showed that its Sycamore quantum computer could solve a problem that no ordinary computer could handle - but now a new algorithm gives non-quantum devices the edge
Quantum computers proved to have ‘quantum advantage’ on some tasks
9 June 2022
Not only do quantum computers have the edge over classical computers on some tasks, but they are also exponentially faster, according to a new mathematical proof
