About

Q

Read full description

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. You can subscribe without creating an account. Prices shown are in US dollars; your local App Store price may differ. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings. Payment is charged to your Apple Account. Quantum hardware access through a provider is subject to that provider's own account, terms and pricing.
