Quantum computing may one day outperform classical machines in solving certain complex problems, but when and how this “quantum advantage” emerges has remained unclear. Now, researchers from Kyoto ...

To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate. Scientists encode these ...

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they ...
