Q-BridgeSeven quantum computing providers in one app
Browse backends from IBM, IonQ, Rigetti, Quantinuum, PASQAL, QuEra and AWS Braket, and submit gate circuits from the web with your own IBM, Quantinuum or Rigetti account. PASQAL and QuEra (via AWS Braket) take analog programs only. The iOS app runs simulators.
Entanglement views use preset reference patterns, and cost and queue figures are rate-card estimates, not live vendor data.
How it works
Live job progress
Simulator jobs stream their status as they move through the queue.
Job monitoring and notifications.
Your own provider accounts
Provider keys are kept in the Keychain on iOS and in memory on the web, and are sent with the requests that need them.
Providers and jobs on one screen.
Rate-card cost estimates
See estimated cost per shot for each backend before you submit.

Compare every product’s plansFrequently asked questions
Do you pay the QPU vendors for me?
No. You use your own provider accounts, and hardware time is billed by the vendor. Q-Bridge shows rate-card estimates before you submit.
Is it really free to start?
Yes. Every app is a free download, and most have a free tier that never expires. On Q-Shield Sentinel, free accounts get a basic assessment; full audits start with the one-time Starter plan.
Can I cancel anytime?
Yes. App Store subscriptions are managed in your Apple ID settings; web subscriptions in your account. Cancel at least 24 hours before renewal and you will not be charged again.
Why do App Store and web prices differ?
Apple sets in-app prices per region and takes a commission; web checkout runs through Stripe. We show web prices here and the app always shows your exact in-app price before you confirm.
Where does my data go?
Paid plans run simulations on your device; free plans use our cloud engine, hosted on AWS in Seoul. AI tutor chats go to OpenAI in the apps and Anthropic on the web, without your name or email; QuantumCareer cover letters include the name on your profile. Deleting your account removes your sign-in data immediately (GDPR Art. 17). The Privacy Policy has the details.
