Google Claims Breakthrough in Quantum Error Correction
Feb 2023 – Quantum computers hold the promise of tackling problems beyond the reach of classical machines, but they are notoriously fragile. Even tiny disturbances can introduce errors into quantum computations. To build a fault-tolerant quantum computer – one that can reliably run long computations – scientists have to keep these errors in check. Google’s Quantum AI team just reported…
