Governed Fault-Tolerant Quantum Computing on Commodity NISQ Hardware: Surface-Code QEC, Universal FTQC Primitives, FTQC Composition, and Chemical Accuracy FTQC across H2, LiH, H2O, BeH2 ... on the IBM Heron r2 and r3 Families of QPUs
Zenodo - Preprint
This paper reports the first end-to-end fault-tolerant quantum computing stack to clear all four strict-FTQC requirements simultaneously on commodity superconducting NISQ silicon, rented through standard IBM Quantum cloud subscription with no purpose-built research machine, no custom decoder, and no magic-state distillation factory. The four requirements: (i) surface-code quantum error correction at distance d≥3 with logical-error rate below the unencoded baseline; (ii) a universal Clifford+T…
This paper reports the first end-to-end fault-tolerant quantum computing stack to clear all four strict-FTQC requirements simultaneously on commodity superconducting NISQ silicon, rented through standard IBM Quantum cloud subscription with no purpose-built research machine, no custom decoder, and no magic-state distillation factory. The four requirements: (i) surface-code quantum error correction at distance d≥3 with logical-error rate below the unencoded baseline; (ii) a universal Clifford+T gate set executed via magic-state injection, with no arbitrary angle physical rotation carrying non-Clifford content on the wire (the algorithm-determined non-Clifford angle never fires on the silicon; the native RZ(θphys) on Heron fires only at Clifford-multiple angles required to compose H, S, T); (iii) heterogeneous primitive composition (teleportation, lattice-surgery CNOT, T-gate, logical memory) on a persistent encoded register; and (iv) runtime admissibility verification on every committed result. All five chips, five chemistry workloads spanning four molecules, and twenty-two governed runs in this paper were executed on the same primitive engine without architectural change.
The architectural shift that makes this work on today’s hardware is the d=1 inversion: a 150-qubit governed encoded register held at substrate distance d=1 on the chip’s physical qubits, with logical fidelity preserved by Seed IQ execution governance over the encoded layer rather than by a larger code distance. Where the standard surface-code paradigm grows physical d quadratically to drive the logical-error rate down...Seed IQ governance acts as an operational substitute for code distance: it delivers the equivalent error-rate reduction in software while leaving the per-gate channel fidelity available for T-gate injection and Clifford operations intact.
The result: the four strict-FTQC requirements hold simultaneously at approximately one physical qubit per logical qubit.Other authorsSee publication -

IBM Social Business VIP “Future of Work” Futurist
- Present
Hand selected by IBM and PureMatter to participate as one of only 30 guest VIPs and social thought leader "Futurists" in a series of events surrounding the IBM Verse Signature Moment launch event in New York City. The three day experience included a PureMatter "Thinkathon" sponsored by IBM, the Verse launch event, a surprise "Mystery Basket" cooking challenge at the International Culinary Center and a half-day "Design Thinking" Camp at Watson HQ – all of which yielded incredible content and…
Hand selected by IBM and PureMatter to participate as one of only 30 guest VIPs and social thought leader "Futurists" in a series of events surrounding the IBM Verse Signature Moment launch event in New York City. The three day experience included a PureMatter "Thinkathon" sponsored by IBM, the Verse launch event, a surprise "Mystery Basket" cooking challenge at the International Culinary Center and a half-day "Design Thinking" Camp at Watson HQ – all of which yielded incredible content and conversation centered around reimagining the future of work.
Together, the event hashtag (#NewWayToWork) trended 1st worldwide. This was also the second highest performing IBM Signature Moment event ever, exceeding the recent IBM & Twitter announcement by 26% on impressions and 13% on mentions on Twitter.
