Quantum simulation, unlocked
Run Your Quantum Circuits Anywhere.
No friction. No lock-in. Large-scale quantum simulation on your own classical hardware — plus real QPUs when you need them.
The platform
One Platform, From First Qubit to Production
Learn, simulate, and run — all in the Quantum Rings ecosystem.
Local Simulation
Simulate hundreds of qubits and millions of operations with high fidelity on hardware you already own. Free for non-commercial use.
Open Quantum
Need real hardware? Run on QPUs from IonQ, IQM, Rigetti, and AQT. Start with $50 in free credits every 90 days.
Quantum 101
A free 14-lecture course taught by an MIT PhD candidate — from the Bloch sphere to a 100-qubit QAOA capstone.
Simulate locally
Large-Scale Quantum Circuits on Your Own Machine
Run circuits that used to require a supercomputer — hundreds of qubits, millions of operations — right on your laptop or workstation. Works with Qiskit, CUDA-Q, and plain Python on Linux, macOS, and Windows.
- Hundreds of qubits
- Millions of operations
- Near-perfect fidelity
- Free for non-commercial use
Run on real hardware
Real QPUs When You Need Them, via Open Quantum
When simulation is not enough, run the same circuits on real quantum processors from leading providers — with transparent pricing and $50 in free credits to start.
- IonQ, IQM, Rigetti & AQT
- $50 free credits every 90 days
- One workflow, sim to QPU
- No lock-in
Learn quantum
Quantum 101: From First Qubit to First Program
