What Is
Open Quantum?
Open Quantum lowers the barriers to using quantum computers with pricing that starts with a free tier for getting started.
Whether you have a QASM file to run directly through the webportal, or want to pip-install our easy to use python package into your existing quantum framework, Open Quantum enables you to start using real quantum computers in moments, without long setup or large upfront commitments.
Flexible access
Use quantum computers starting with a free tier and scaling to higher capacity as your workloads grow.
Run Online
Easily execute your QASM files across various quantum systems.
Seamless Integration
Pip install packages into your existing quantum framework.
Fast Setup
Get up and running on real quantum computers or HPC simulations in moments.

What is Free?
Real quantum hardware at no cost. No credit card, no hidden fees.
The offer
$50 in Spark Credits
Claim every 90 days with one click in your dashboard. Run on real QPUs from IonQ, Rigetti, and more!
- Instant access — Web dashboard or Python SDK, no complex setup.
- Same hardware as paid tier — High-quality QPUs with usage limits tied to your credits.
Who it's for
Students, researchers, hobbyists, and developers — bridge the gap from simulators to real quantum execution.
Earn more credits
Beyond the 90-day refresh, you can unlock extra credits:
Referring a Friend
$50 bonus credits each time someone signs up with your referral link.
Milestones
Earn additional credits for completing challenges, which will be published periodically.
How is it Free?
A collaborative ecosystem that makes high-end quantum compute affordable for everyone.
Why it's free
Our partnership with qBitTensor Labs and the Bittensor ecosystem powers the free tier, connecting you to a global network of quantum hardware contributors.
How it works
When you run jobs on the Free tier:
- 1
Your jobs run on our network
Your circuits are efficiently processed across a decentralized network of resources, optimized for real QPUs and high-fidelity simulators.
- 2
Anonymized data helps the community
Your job data (aggregated, anonymized) improves algorithms, calibration, and platform performance for everyone.
- 3
We ask you to cite us
Publications and presentations using results from Open Quantum should provide proper citation. For more information, see https://www.openquantum.com/citation.
The result
This community-driven model subsidizes access so you can experiment without paying upfront.
Scale up
Need more? Premium tiers offer private runs, higher volume, and priority queuing when you scale up.
How Does It Work?
Sign up
Create your free account in under a minute. No credit card needed.
Claim your credits
Log in and claim your $50 in Spark credits every 90 days. Earn more via referrals or milestones.
Choose your path
Use the intuitive web portal to upload circuits (QASM or similar) or integrate our Python SDK into your workflow (works seamlessly with Qiskit, PennyLane, etc.).
Submit jobs
Pick from available QPUs or high-fidelity simulators.
Receive results
Get the results from your quantum executions quickly, online or integrated into your code environment.
Everything happens through one unified API — no vendor-specific accounts or long queues. If credits run low between claims, top up via premium purchase or keep earning through community actions. Open Quantum keeps things simple so you can focus on innovation instead of infrastructure.
