China is racing to harden its quantum ambitions on two fronts at once, pairing more powerful quantum processors with new ...

Quantum computers promise to tackle problems that are unsolvable for today’s machines, but their basic units (qubits) are incredibly fragile. Even a tiny disturbance can wipe out the entire delicate ...

A quantum bit inspired by Schrödinger’s cat has managed to resist making errors for an unusually long time in a quantum computing experiment. This may make it a promising building block for more ...
