TechnologySpies may be storing data to decrypt with a future quantum computer Quantum computers may one day break encryption, and security researchers say intelligence agencies may already be storing encrypted data with a plan to crack it in future News
PhysicsWhy it might be impossible to build a practical quantum computer After “quantum supremacy”, the next step is scaling up and mastering the errors that dog qubits. But some researchers reckon the noise might always to be too high for useful quantum computers Features
