• Run tab: circuit, Run and result on one screen. The app opens on Run with the Bell circuit filled in. Pick a backend and shots, tap Run and watch the job go from queued to done with its measurement counts right below.
• Run before you sign up: up to 3 circuits a day on the cloud simulator without an account (8 qubits, 1,024 shots). Sign in for 100 jobs a day and the Jobs list. Sign in with Apple is available.
• OpenQASM editor on the Free plan. Free keeps the 8-qubit simulator cap; Pro runs up to 20 qubits.
• Jobs › Provider jobs: add your own IBM Quantum or Amazon Braket key and see up to 20 recent jobs on that account, with status, backend and measurement counts once finished. Read-only; the key stays in your device's Keychain. Every plan.
• Three tabs: Run · Jobs · More. Nothing was removed. Tools, the classic dashboard, the Team workspace and Settings are under More; Emergency stop is in the Jobs toolbar. The intro is one page.

• New: Where a quantum job runs. Follow one job along its physical path. An interactive illustration of a dilution refrigerator shows the circuit you submit leaving room temperature as microwave pulses, travelling down through each cooling stage to a chip held near ten millikelvin, and the measurement signal coming back up. Step through the stages or play the whole path.
• See why results differ between backends: shots, queue times and noise come from the physical machine. Superconducting machines look like this figure; trapped-ion and neutral-atom machines use lasers and vacuum systems instead.
• Find it at the top of Tools › Visualization. Available on every plan, and in guest mode without an account.
• Built into the app and works offline: it makes no network request and sends nothing. The stages and temperatures are typical values, not live data or readings from any provider.
• Follows light and dark mode, respects Reduce Motion, and VoiceOver reads a description of the figure. In all seven languages.

• 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.

About Q-Bridge: Quantum Workbench
Q-Bridge is a quantum job workbench for iPhone, iPad and Mac, for developers and researchers who write quantum circuits, submit them and want to follow the results in one place.
WHAT YOU CAN DO
• Run a circuit — Paste OpenQASM (the Bell circuit is already filled in), tap Run and see the counts on the same screen. The editor is on every plan.
• Follow every job live — Each job moves from queued to running to completed on screen, and the list updates the moment a status changes.
• Your provider jobs, read-only — Jobs › Provider jobs lists up to 20 recent jobs from your own IBM Quantum or Amazon Braket account: status, the provider's status, backend, created time, and measurement counts once a job finishes. Nothing is submitted, cancelled or deleted. Your key stays in the device Keychain on iPhone, iPad and Mac, never on Q-Bridge servers. Every plan.
• 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, with the job's history and details.
• Cloud simulator — Circuits run on our noiseless cloud simulator, not on your device. The qubit limit depends on your plan.
• 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 — Provider API keys you add stay in your device's Keychain; none is bundled, and the simulator needs none. They are sent only with requests that need them: reading your provider jobs, or the catalog and jobs you submit to a provider (Pro).
• Backend suggestions on your device (Pro) — On supported devices, Bridge Advisor suggests a backend with Apple's on-device model; your circuit is not sent anywhere for it.
• 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 before you create an account.
BUILT FOR APPLE PLATFORMS
