正文提要
Quantum computers hold great promise for applications from drug discovery to cybersecurity. Yet figuring out what would give quantum computers their edge over everyday "classical" computers is a subtle problem. A new theoretical study led by researchers at the Cavendish Laboratory shows that quantum computers are harder to make powerful than previously assumed while offering the clearest picture yet of what actually makes them work.
