The quantum computing sector is maturing past simple raw qubit count announcements toward standardized measures of error mitigation and gate fidelity. The consensus metric is shifting to Quantum Volume, which reflects real-world processing capability for complex algorithms.
Logical Qubit Milestones
Recent hardware demonstrations successfully implemented active error correction to create fault-tolerant logical qubits with lifespans exceeding physical components. Commercial utility for chemical simulation and complex portfolio optimization is projected within four to six years.
