Documentation

QuantumLedger documentation

Bind every quantum run to the exact calibration and hardware state that produced it — so results are reproducible, comparable, shareable and auditable across vendors. These docs cover the concepts, the workflows, every page of the app, the libraries and the full API.

Quickstart →

Shell

pip install quantumledger

Getting started

Record and reproduce your first quantum run in under five minutes — offline, no account.

Provenance, content-addressing, the Merkle run-hash and the tamper-evident ledger.

The @ql.capture decorator, the local ledger and the vendor connector plugins.

Reproduce & drift

Re-run against a drifted device state; read the Hellinger score, verdict and diff.

Compliance & attestations

Frameworks-as-data, evidence rules, gaps, and signed, verifiable attestations.

Every REST endpoint with example requests and responses.

The ql command-line tool: init, capture, list, show, reproduce, push.

Deployment & self-hosting

docker-compose, environment variables, SQLite vs PostgreSQL, air-gapped mode.
