qiskit_braket_provider.providers.BraketAwsBackend¶

class BraketAwsBackend(arn=None, provider=None, name=None, description=None, online_date=None, backend_version=None, *, device=None, **fields)[source]¶

Runs quantum circuits on the Amazon Braket service.

Initialize the backend.

Example

>>> provider = BraketProvider()
>>> backend = provider.get_backend("SV1")
>>> transpiled_circuit = transpile(circuit, backend=backend)
>>> backend.run(transpiled_circuit, shots=10).result().get_counts()
{"100": 10, "001": 10}

Parameters:

arn (str | None) – ARN of the Braket device. Default: None.
provider – Qiskit provider for this backend. Default: None.
name (str | None) – Name of backend. Default: None.
description (str | None) – Description of backend. Default: None.
online_date (datetime | None) – Online date. Default: None.
backend_version (str | None) – Backend version. Default: None.
device (AwsDevice | None) – Braket device instance. Default: None.
**fields – Extra arguments.

__init__(arn=None, provider=None, name=None, description=None, online_date=None, backend_version=None, *, device=None, **fields)[source]¶
