Q-Bridge: Quantum Workbench
Submit and track quantum jobs
Free · In‑App Purchases
Write OpenQASM, run it on the cloud simulator and follow each job from queued to done in real time. Compare backends from seven quantum providers in one app.
Q-Bridge is a quantum job workbench for iPhone, iPad and Mac. It is built for developers and researchers who write quantum circuits, submit them, and want to see what happens next without switching between vendor consoles.
WHAT YOU CAN DO
• Submit jobs — Pick a backend and submit a job from the Dashboard, or write and paste OpenQASM in the built-in editor (Pro).
• Follow every job in real time — Each job moves from queued to running to completed on screen as it happens. Your job list updates the moment a status changes, with no manual refresh.
• Emergency stop — One tap cancels all of your active jobs, and the app shows which jobs, if any, could not be stopped.
• Open real results — Finished simulator jobs return measurement counts you can inspect right away, together with the job's history and details.
• Cloud simulator — Circuits run on our cloud simulator (not on your device). The qubit limit depends on your plan, and the simulator is noiseless.
• Compare backends from seven providers (Pro) — Browse backends from IBM Quantum, IonQ, Rigetti, Quantinuum, PASQAL, QuEra and Amazon Braket side by side in one catalog.
• Bring your own provider credentials (Pro) — Provider API keys you add are stored in the Keychain on your device. No provider key is bundled with the app, and you never need one to use the simulator. They are sent only with requests that need them — the provider catalog or a job you submit to a provider.
• Backend suggestions on your device (Pro) — On supported devices, Bridge Advisor suggests a backend for your circuit using Apple's on-device model, so your circuit is not sent anywhere to get a suggestion.
• Bloch sphere — Visualize single-qubit states interactively, on every plan.
• Easy start — A short intro you can skip or replay from Settings, and a guest mode to look around before you create an account.
BUILT FOR APPLE PLATFORMS
Native SwiftUI on iPhone, iPad and Mac, with Liquid Glass design. Universal Purchase: one subscription covers iPhone, iPad and Mac. Available in English, Korean, Japanese, Simplified Chinese, Spanish, French and German.
PRIVACY
No ads and no third-party tracking. The camera is used only when you choose to scan a QR code to pair a gateway. Provider keys stay in the Keychain. Creating an account requires you to be 13 or older.
PLANS
• Free — Cloud simulator jobs with live tracking, emergency stop and the Bloch sphere.
• Pro — $24.99/month or $159.99/year. Adds the OpenQASM editor, the seven-provider catalog with your own credentials, Bridge Advisor and more tools, plus a higher simulator limit.
• Team — $69.99/month or $549.99/year. Everything in Pro, plus the Team workspace and Team tools.
• Enterprise — Contact sales. Not sold in the app.

Version 10.2.3
• New Job, ready to run: the backend list refreshes every time you open it, the cloud simulator is always listed and pre-selected, and the job name you enter is the name you see in Jobs and on the Dashboard.
• Easier to read: Jobs filters sit in a compact grid, Bridge Advisor suggestions are shown as formatted text, Dashboard job cards summarize results as |11> 52% · |00> 48%, and providers appear under their proper names (IBM Quantum, IonQ, PASQAL, QuEra, Amazon Braket).
• Subscribe your way: choose monthly or yearly billing in the app and subscribe without creating an account first.
• Purchases and restores now sync with your account more reliably.
• Clearer results: a job that returns no measurement data now shows a "Result unavailable" card instead of an empty chart, and features the server does not offer yet say so plainly.
• Emergency stop you can trust: one tap now cancels all your active jobs on the server, and you see exactly which ones, if any, could not be stopped.
• Smoother start: skip the intro, replay it any time from Settings, or look around as a guest before creating an account.
• Clearer labels on analysis tools: topology maps, crosstalk, noise analysis and the decoder estimate now say plainly whether they show reference data, a model or a heuristic score.
• Bridge Advisor now always recommends a backend that exists in the catalog.
• Safer connections: every request now goes through the app's certificate-pinned connection, provider keys are sent only with requests that need them, live job updates use a short-lived, single-use pass, and the gateway pairing token is no longer stored on the device.
• Dashboard and New Job now agree: the Online badge and the Connected Backends card count the same backends the New Job sheet offers, including the cloud simulator.
• Topology legends now say "Reference fidelity" so it is clear they show reference values, not measurements from a device.
• Sign-up now asks for your real date of birth (13+), and sign-in errors are clearer.
• Camera permission explained: the camera is used only to scan a QR code when you pair a gateway.
• Signing out resets every screen, the OpenQASM editor's Run button label is fixed, the Cancel button on the New Job sheet is no longer cut off, plus localization fixes in all seven languages.
• Clearer plan limits: the editor shows the cloud simulator limit (8 qubits on Free, 20 on paid plans) separately from the per-job limit for hardware jobs sent through your own provider account, and each job is checked against the limit of the backend you pick before it is sent. Plan descriptions in the app now list only these enforced limits.
