Adam Riess was sure he’d spotted a blatant error in his results. It was 1997, and the young post-doc’s measurements of distant, exploding stars implied that the ...

Reliable quantum information processing in the face of errors is a major fundamental and technological challenge. Quantum error correction protects quantum states by ...
