Quantum Computing for All
Quantum hardware without the overhead.
Run on QPUs from IonQ, Rigetti, IQM, and AQT. Free to start.
What Is
Open Quantum?
Open Quantum connects you to quantum computers from IonQ, Rigetti, IQM, and AQT through a single API, at half the cost of going direct. No vendor accounts, no complex setup. You can be running on real hardware in minutes.
Upload a QASM file through the web portal, or pip-install our Python package into your existing Qiskit or PennyLane workflow. Either way, you're on real QPUs fast.
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.
Partners
Backed by leading quantum hardware providers and qBitTensor Labs
Two Ways to Run
Same quantum hardware, same API. Choose the execution path that fits your needs.
Public Compute
Half the price. Same hardware.
Public Compute routes your jobs through qBitTensor Labs, delivering the same QPU results at half the cost of Private Compute. Start free with $50 of quantum compute, claimable every 90 days.
- Real QPUs — IonQ, Rigetti, IQM, AQT, and more through one API.
- Free to start — Claim Spark Credits from your dashboard. No credit card needed.
- Data is anonymized — Your circuits are routed through the network with privacy protections.
Private Compute
Full privacy. Direct access.
Private Compute runs your jobs on dedicated infrastructure managed by Quantum Rings, with full data privacy and priority queue access. Built for production workloads and sensitive IP.
- Fully private — Your circuits and results stay between you and the hardware.
- Priority access — Optional priority queuing for faster turnaround.
- Pay with Full Credits — Purchase credits as needed, valid for one year.
Earn more Spark Credits
Beyond the 90-day refresh, you can earn additional credits for Public Compute:

How Public Compute Works
Powered by qBitTensor Labs, delivering real quantum hardware at a lower cost.
The network
Public Compute is powered by qBitTensor Labs' Quantum Compute Subnet 48. This is what enables the lower pricing: shared infrastructure, lower overhead.
When you submit a job
- 1
Your job is routed through the network
Your circuits are routed through qBitTensor Labs to real QPUs from leading providers.
- 2
Anonymized data strengthens the network
Aggregated, anonymized job data improves calibration, algorithms, and platform performance across the ecosystem.
- 3
We ask you to cite us
Publications and presentations using results from Open Quantum should provide proper citation. For more information, see openquantum.com/citation.
Need full privacy?
Switch to Private Compute for dedicated infrastructure, full data privacy, and priority queuing — all through the same API.
How Does It Work?
Sign up
Create your free account in under a minute. No credit card needed.
Claim your credits
Claim $50 of free quantum compute every 90 days, or purchase Full Credits for either tier.
Choose your path
Upload circuits through the web portal or integrate our Python SDK into your workflow. Select Public Compute or Private Compute based on your needs.
Submit jobs
Pick from available QPUs across multiple providers.
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. Start with Public Compute and Spark Credits, or go straight to Private Compute with Full Credits. Switch between them anytime. Open Quantum keeps things simple so you can focus on your research instead of infrastructure.
