A device smaller than a grain of dust is emerging as a surprisingly powerful candidate to reshape how quantum computers are built and scaled. Instead of relying on room-filling optics and fragile lab ...

Quantum computers based on ions or atoms have one major advantage: The qubits themselves aren’t manufactured, and there’s no device-to-device variability among atoms. Every atom is the same and should ...

China is racing to harden its quantum ambitions on two fronts at once, pairing more powerful quantum processors with new cryptographic tools designed to survive a future of code-breaking machines.

On Thursday, Microsoft’s Azure Quantum group announced that it has settled on a plan for getting error correction on quantum computers. While the company pursues ...
