provenova — SDK & CLI

The open-source client for Provenova, the vendor-neutral system of record for quantum computing. Capture every quantum run — circuit, backend, calibration snapshot and result — into an immutable, offline-verifiable local ledger, then reproduce, score and publish.

pip install "provenova[aer]"

import provenova as ql
from qiskit_aer import AerSimulator

@ql.capture(project="bell")
def run():
    return AerSimulator().run(qc, shots=4096)

$ ql list                                  # inspect your local ledger
$ ql reproduce <id> --days 90 --profile bad_day
$ ql push                                  # sync to a hosted / self-hosted server

What you get

• @ql.capture decorator / context manager — records runs from existing code with no rewrites; fully offline, no account required.
• Vendor connectors (plugin system): Qiskit Aer, IBM Qiskit Runtime, Amazon Braket, Azure Quantum, IonQ. Extras: [aer], [qiskit_runtime], [braket], [azure].
• Local ledger — SQLite, schema-identical to the hosted store; every run bound to the exact calibration that produced it via a Merkle run_hash that verifies offline.
• ql CLI — list, show, reproduce (with deterministic drift profiles), and content-hash-idempotent push.
• Open provenance format (qlprov/run/1.0) — portable JSON that verifies its own hash without any server.
