qiskit_braket_provider.providers.BraketLocalBackend¶

class BraketLocalBackend(name='default', *, device=None, target=None, qubit_labels=None, **fields)[source]¶

Runs quantum circuits on a Braket local simulator or device emulator.

Wraps a LocalSimulator selected by name, or a pre-built device such as the emulator from AwsDevice.emulator() when one is given.

Initialize the backend.

Example

>>> device = LocalSimulator()                    #Local State Vector Simulator
>>> device = LocalSimulator("default")           #Local State Vector Simulator
>>> device = LocalSimulator(name="default")      #Local State Vector Simulator
>>> device = LocalSimulator(name="braket_sv")    #Local State Vector Simulator
>>> device = LocalSimulator(name="braket_dm")    #Local Density Matrix Simulator

Parameters:

name (str) – Name of backend. Default: default.
device (Device | None) – A pre-built local device to run on, such as the emulator from AwsDevice.emulator(). Defaults to a LocalSimulator selected by name. Default: None.
target (Target | None) – Target for the backend. Built from the local simulator when omitted, required when device is supplied. Default: None.
qubit_labels (tuple[int, ...] | None) – Qubit labels of the device, in ascending order. Default: None.
**fields – Extra arguments.

__init__(name='default', *, device=None, target=None, qubit_labels=None, **fields)[source]¶

Initialize the backend.

Example

>>> device = LocalSimulator()                    #Local State Vector Simulator
>>> device = LocalSimulator("default")           #Local State Vector Simulator
>>> device = LocalSimulator(name="default")      #Local State Vector Simulator
>>> device = LocalSimulator(name="braket_sv")    #Local State Vector Simulator
>>> device = LocalSimulator(name="braket_dm")    #Local Density Matrix Simulator

Parameters:

name (str) – Name of backend. Default: default.
device (Device | None) – A pre-built local device to run on, such as the emulator from AwsDevice.emulator(). Defaults to a LocalSimulator selected by name. Default: None.
target (Target | None) – Target for the backend. Built from the local simulator when omitted, required when device is supplied. Default: None.
qubit_labels (tuple[int, ...] | None) – Qubit labels of the device, in ascending order. Default: None.
**fields – Extra arguments.
