State vector simulator (SV1)

SV1 is an on-demand, high-performance, universal state vector simulator. It can simulate circuits of up to 34 qubits. You can expect a 34-qubit, dense, and square circuit (circuit depth = 34) to take approximately 1–2 hours to complete, depending on the type of gates used and other factors. Circuits with all-to-all gates are well suited for SV1. It returns results in forms such as a full state vector or an array of amplitudes.

SV1 has a maximum runtime of 6 hours. It has a default of 35 concurrent quantum tasks, and a maximum of 100 (50 in us-west-1 and eu-west-2) concurrent quantum tasks.

SV1 results

SV1 can provide the following results, given the specified number of shots:

• Sample: Shots > 0

• Expectation: Shots >= 0

• Variance: Shots >= 0

• Probability: Shots > 0

• Amplitude: Shots = 0

• Adjoint Gradient: Shots = 0

For more about results, see Result types.

SV1 is always available, it runs your circuits on demand, and it can run multiple circuits in parallel. The runtime scales linearly with the number of operations and exponentially with the number of qubits. The number of shots has a small impact on the runtime. To learn more, visit Compare simulators.

Simulators support all gates in the Braket SDK, but QPU devices support a smaller subset. You can find the supported gates of a device in the device properties.
