Product tour

A screen-by-screen guide to every page in the web app and what each button does. The top navigation bar is always present: Home · Records · State of Quantum Hardware · Compliance · Trust Center · Docs (plus Admin for superadmins), with your account and plan on the right.

Home / dashboard (/)

Signed out, this is a landing page. Signed in, it's your dashboard: recent runs and summary stats (run count, reproductions, published cards). Use it as a jumping-off point to Records or Compliance.

Records (/app/records)

A table of every run in your workspace — status, backend, shots, and created time. Click a row to open its detail. If the table is empty, you haven't captured or pushed any runs yet; see Capturing runs.

Record detail (/app/records/<run_id>)

The full provenance of one run:

  • Provenance — circuit, backend, calibration snapshot, and the run_hash / chain hashes. This is the Merkle-bound, offline-verifiable identity of the run.
  • Result distribution — the measured bitstring counts.
  • Reproduce (form + button) — choose days to drift and a profile (typical / bad_day / recalibrated) and submit to re-run the circuit against a drifted device state. See Reproduce & drift.
  • Reproduction report — after reproducing: the Hellinger-fidelity score, the verdict, and the diff (calibration drift, transpilation delta, top bitstring shifts).
  • Publish (button) — turn this run into a public Result Card.

State of Quantum Hardware (/leaderboard)

The public cross-vendor leaderboard, ranking devices by a calibration metric you can switch (2-qubit error, T1, T2, readout fidelity). Backed by the public corpus.

Compliance (/app/compliance)

The compliance console (Pro+). A "How it works" panel and a status legend sit at the top, followed by a card per framework.

  • Enable — turn a framework on for your workspace and evaluate it for the first time.
  • Evaluate all — recompute every enabled framework against your current runs. Safe to run repeatedly.
  • Re-evaluate (per framework) — recompute just that one.
  • View controls & gaps — open the framework detail page.
  • Attest — appears when a framework passes; issues a signed attestation.

Framework detail (/app/compliance/frameworks/<id>)

The drill-down: an overall pass/gap rollup with a progress bar, then every control with its ✓/✗ status, what the standard requires, each check in plain English (failing ones marked), remediation for gaps, and the evidence collected (with source and content hash). Full concepts in Compliance.

Attestations table

Below the frameworks: every attestation you've issued, its evidence root, active/revoked status, and a Verify link that checks the signature.

Trust Center (/trust/<org>)

A public page for an organization showing its framework statuses and active, signed attestations — so partners can verify your compliance posture without contacting you. Revoked attestations stop appearing.

Result card (/cards/<slug>)

The public face of a published run: title, summary, provenance, distribution, badges, an embed snippet, and citation formats (BibTeX/RIS). See Result cards & badges.

Settings (/app/settings)

Your account: profile and password, two-factor authentication (TOTP — set up via QR code), and API keys for pushing runs from the SDK (ql login --token …). Generate a key here, copy it once, and store it safely.

Admin (/app/admin, superadmin only)

Organization management: view every org and its effective plan, and change plans (upgrade/downgrade).

Docs (/docs)

This documentation. The left sidebar groups every page; reference pages (CLI, API, Frameworks) are generated live from the running system.
