What was this quantum result made of?
One signed bill of materials answers.
Record every stage of one computation in one signed list; swap any stage and the list no longer verifies.
An operations stack runs the job — submits the program, manages the device, returns the counts. A QBOM signs what the result is made of: which compiled circuit ran (and that it was equivalent to the source), against which calibration, on a register prepared how, under which error mitigation, with which decode. Each of those stages already emits a signed receipt here.
A Quantum Bill of Materials assembles the stage receipts of one computation into a single signed, content-addressed provenance manifest — with a total-energy roll-up and an operator-envelope export a job/result exchange can carry. Verification is layered: the bill verifies its own signature and provenance root, and presented with the actual receipts, it confirms every listed stage binds a receipt that itself verifies — so a swapped or forged stage breaks the bill. Byte-exact and reproducible: the same computation rebuilds the same root from the git repo. The synthesis of the whole quantum-ops receipt family.
The bill of materials · signed stages, one manifest
The certificate is real · operator-envelope sidecar
A quantum result that carries its own provenance — signed, with an energy slot, verifiable
The bill panel runs two stages on the site's live solvers — a circuit routed onto a coupling graph
and proven equivalent, and a stochastic trap load rearranged defect-free — and bundles
them with a calibration, an error mitigation, and a decode, each a signed stage receipt. The manifest
lists every stage by (kind, receipt hash, joules), rolls up the total energy, and is
itself signed; its provenance root is a content hash anyone can recompute. The second panel
shows the check has teeth — swap one stage for a forgery and the bill no longer binds — and prints
the operator envelope, the provenance sidecar a job/result exchange can carry alongside the
operations stack's own record. A quantum result you can hand an auditor with one verifiable statement
of everything it was made of and what it cost, reproducible from the git repo.
Where it lives. The engine is reference code in the open-standards repo, Apache-2.0. Energy: not metered. Receipts sealed in this tab carry a placeholder joule value, so the page shows none.
