IBM Uses AI to Discover 465 New Quantum Error Correction Codes
IBM Research built OpenEvolve, an open-source framework pairing large language models with evolutionary algorithms to search the algebraic space of quantum error correction codes. Applied to bivariate bicycle codes on IBM's fault-tolerant roadmap, the system identified 465 new candidates — including a record-breaking code supporting 50 logical qubits, more than three times the previous best of 16. The framework is fully open-sourced on GitHub to accelerate the broader research community.
