Capabilities

Simulation

Simulate quantum circuits on CPU or GPU backends.

The simulation endpoint runs a quantum circuit and returns measurement results, statevectors, or density matrices depending on the chosen method.

Backends

BackendDescriptionAvailability
aerCPU-based Qiskit Aer simulatorAll plans
cudaqGPU-accelerated CUDA-Q simulatorPro and above
autoAutomatically selects the best backendPro and above

Free-tier users are limited to the aer backend with a maximum of 16 qubits. Paid plans support GPU simulation up to 29 qubits.

Simulation methods

MethodDescription
qasmExecutes the circuit with measurement sampling. Returns counts.
statevectorReturns the full quantum state as a complex vector.
density_matrixReturns the density matrix representation.
