Quantum Computers on Open Quantum

Access QPUs from leading hardware providers through one unified interface. Compare live status, explore each device, and run circuits with $50 of free quantum compute. Prototype on free simulators (beta), then run the same circuit on real QPUs.

Simulators

Beta

Prototype free during beta, then run the same circuit on real QPUs. Compare all simulators. The Quantum Rings simulator is proven on the 2019 quantum-supremacy circuits, see the research.
