D-Wave plans a 49-qubit gate-model system that cuts errors 20-fold in 2027

Due 2027

D-Wave says it will complete in 2027 a 49-qubit gate-model system expected to make errors 20 times rarer than on its bare physical qubits, using error correction (spreading information over several qubits so mistakes can be caught and fixed).
