Algorithmic Qubits (Error-Corrected Logical Qubits)
Google Quantum AI's metric for measuring progress toward fault-tolerant quantum computing, based on the error suppression factor Lambda achieved by surface code logical qubits. On the Willow processor, a distance-7 surface code using 101 qubits achieved a logical error rate of 0.143% per cycle, with errors suppressed by a factor of 2.14 for each increase in code distance by 2, operating below the surface code threshold.[1]
