In plain English: Quantum Bond works the OTC fixed-income market — it scans for liquidity across venues, finds best execution, scores the credit, and nets the settlement. Eight classical tools, four quantum-accelerated, every print PQC-sealed to a WORM ledger the moment it's struck.
A corporate bond's real price lives in a dozen disconnected pools. Miss the best bid and best-execution becomes a number you can't justify.
MiFID II RTS 27/28 and FINRA want proof you swept the market. A screenshot of one quote isn't proof — it's an exposure.
Trade, spread, venue, time — the audit chain a regulator asks for, gone the moment the next ticket lands. SEC 17a-4 wants it for seven years.
Deterministic QuantLib analytics as the source of truth, with quantum acceleration where it earns escalation to a real IBM QPU — every result carrying a verifiable job ID when it runs on silicon.
YTM, clean price, duration and convexity from a deterministic DCF engine — the mark you can recompute by hand.
Best-of-quotes across OTC venues via a Grover search — the best bid and best ask, found in O(√N) not O(N).
Z-spread decomposition (QAE) and a quantum-kernel credit score (QSVM) — rich/cheap and risk, on the same ticket.
T+1 / T+0 netting optimization (QAOA) and automatic trade reconciliation — fewer fails, every step recorded.
A working OTC blotter. Enter an order and the desk prices the bond, sweeps simulated venues for the best bid and ask, computes effective spread and market impact, scores the credit, and seals a trade ticket — exactly as the live agent seals every print to its WORM ledger.
| Venue | Type | Bid | Ask | Size |

QuantLib DCF sets the fair price, duration and convexity — the recomputable baseline every quote is measured against.
A Grover search finds the best bid and ask across venues; QAE prices the spread, QSVM scores the credit. Escalates to a real IBM QPU when it earns it.
Order, execution, venue and spread sealed Ed25519 + ML-DSA/SLH-DSA to a WORM ledger — best-ex proof, 7-year retention.
Per-tool, the quantum method and the deterministic engine it runs against — the boundary documented for IBM technical validation.
