This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...

Quantum computing has long felt like a perpetual promise — a mysteriously powerful technology that’s always “about 10 years away.” If you tuned it out, you weren’t alone. But something has shifted ...

Picture a quantum computer. Are you imagining an ordinary computer, but somehow just better? If so, that would be a mistake, because quantum computers are fundamentally different. They rely on exotic ...
