IBM released Condor in December 2023 as the first single chip to exceed 1,000 physical qubits (1,121). The milestone demonstrated that superconducting qubit fabrication could scale to four digits while maintaining yield and connectivity.

Condor was part of IBM's roadmap toward error-corrected logical qubits, with Heron and future systems designed to improve gate fidelities and reduce crosstalk.
