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

Parameters:

device (AwsDevice) – Braket device class
provider (Optional[Provider]) – Qiskit provider for this backend
name (Optional[str]) – name of backend
description (Optional[str]) – description of backend
online_date (Optional[datetime]) – online date
backend_version (Optional[str]) – backend version
**fields – other arguments
