Researchers from IBM Quantum, the Joint Center for Quantum Information and Computer Science (QuICS / NIST / UMD), and MIT have developed a neuro-symbolic search framework that pairs large language model (LLM) agents with deterministic solvers to map uncharted magic-state distillation protocols. Detailed in a preprint titled Symmetry and AI-assisted discovery of magic-state factories, the team uncovered 699 factory classes—including 564 previously unknown protocols—delivering non-Clifford states with record-low physical resource footprints.
| Key Magic-State Factory Milestones Discovered | ||
|---|---|---|
| Factory Class [[n, k, d]] | Output Gate & Metrics | Technical & Efficiency Significance |
| [[63, 11, 3]] | 11 pure T states (γ = 1.589) | Lowest known overhead exponent among pure-T distillation protocols consuming ≤ 100 inputs (5.73 inputs/output). |
| [[850, 128, 6]] | 128 pure T states (γ = 1.057) | Lowest reported overhead exponent for any known distillation protocol… |
