Module with implementation of the local Braket simulator.

Classes

LocalAmazonBraketBackend

Class for handling Amazon Braket's local simulator.
class LocalAmazonBraketBackend

Bases: Backend

Class for handling Amazon Braket’s local simulator.

__init__(device_to_simulate: DeviceData | None = None, *, compiler: Compiler | None = None, layout_synthesizer: LayoutSynthesizer | None = None) → None

Initialize a local Braket Backend.

The backend calculates the full state vector or density matrix of the given circuit, and uses this to find the probabilities for each possible state in the Hilbert space.

Parameters:

  • method – Method to use in the simulator.

  • device_to_simulate (DeviceData | None) – Device data to simulate noise from. If None, no noise is applied.

  • compiler (Compiler | None) – Compiler for changing into universal gates. Defaults to the Yordanov compiler.

  • layout_synthesizer (LayoutSynthesizer | None) – Layout synthesizer to change into topology. Defaults to None

Return type:

None

property name: str

Name of the backend.

run(circuits: Circuit | Sequence[Circuit], shots: int | None) → SimulatedJob

Run circuit on the backend.

Parameters:

  • circuits (Circuit | Sequence[Circuit]) – circuits to run on backend.

  • shots (int | None) – number of shots. Must be a positive integer.

Return type:

SimulatedJob

supports_shots_equals_none() → bool

Return whether the backend supports shots = None.

Braket backends do not support exact simulations without shots.

Return type:

bool
