Backends

The Backends catalog (/backends) lists every quantum processor and simulator you can run circuits on.

Browsing the catalog

• Card or list view — toggle between a card grid and a compact table; your choice is remembered for the session.
• Filter — by provider and other categories.
• Sort — by provider, qubit count, or type.
• Each entry shows an online/offline status badge and, once you open it, specs such as qubit count, topology, native gates, gate/readout fidelities, coherence times, and a qubit connectivity map where available.

Backends come from three providers:

Provider	Notes
IQM	Garnet, Emerald, and Sirius processors, each with a free :mock simulator counterpart. All six are wired up for job submission today.
Rigetti	Listed in the catalog; job submission isn't available yet.
IBM Quantum	Listed in the catalog with live calibration data; job submission isn't available yet.

Submitting a job from a backend card

Open any IQM card and expand Connect to <device>:

• Simulators (:mock devices) run with no API key required — click Submit a sample circuit to open the same submission form used on the Dashboard, or follow the linked Google Colab quickstart notebook.
• Real quantum processors require a Light Rider API key. If you haven't generated one yet, the panel links straight to Settings → API Keys (details). Once you have a key, the panel shows a ready-to-run Python snippet that posts your circuit directly to the platform API, plus the same Submit a sample circuit button for testing from the dashboard itself.

Real-hardware submissions are metered in compute tokens per shot and require having purchased tokens at least once.

What "submit a job" actually does

The submission form (used on the Dashboard, the Backends catalog, and the Jobs page) lets you:

1. Pick a sample circuit — an H gate (1-qubit superposition) or a Bell state (2-qubit entangled pair).
2. Choose a shot count.
3. Submit — the job appears immediately with a Pending/Waiting/Processing status, then live-updates to Completed, Failed, or Aborted.

Once a job completes, its measurement results appear in the same view — see Jobs & results for how to read them, and how to submit circuits programmatically instead of through the dashboard.

Next steps

• Jobs & results — track every submission and read measurement counts.
• API keys — authenticate requests made outside the dashboard.
