AwsQuantumTask factory method that serializes a quantum task specification (either a quantum circuit or annealing problem), submits it to Amazon Braket, and returns back an AwsQuantumTask tracking the execution.

Parameters:

aws_session (AwsSession) – AwsSession to connect to AWS with.
device_arn (str) – The ARN of the quantum device.
task_specification (Union[Circuit, Problem, OpenQASMProgram, BlackbirdProgram, PulseSequence, AnalogHamiltonianSimulation]) – # noqa The specification of the quantum task to run on device.
s3_destination_folder (AwsSession.S3DestinationFolder) – NamedTuple, with bucket for index 0 and key for index 1, that specifies the Amazon S3 bucket and folder to store quantum task results in.
shots (int) – The number of times to run the quantum task on the device. If the device is a simulator, this implies the state is sampled N times, where N = shots. shots=0 is only available on simulators and means that the simulator will compute the exact results based on the quantum task specification.
device_parameters (dict[str, Any] | None) – Additional parameters to send to the device.
disable_qubit_rewiring (bool) – Whether to run the circuit with the exact qubits chosen, without any rewiring downstream, if this is supported by the device. Only applies to digital, gate-based circuits (as opposed to annealing problems). If True, no qubit rewiring is allowed; if False, qubit rewiring is allowed. Default: False
tags (dict[str, str] | None) – Tags, which are Key-Value pairs to add to this quantum task. An example would be: {“state”: “washington”}
inputs (dict[str, float] | None) – Inputs to be passed along with the IR. If the IR supports inputs, the inputs will be updated with this value. Default: {}.
gate_definitions (dict[tuple[Gate, QubitSet], PulseSequence] | None) – A dict of user defined gate calibrations. Each calibration is defined for a particular Gate on a particular QubitSet and is represented by a PulseSequence. Default: None.
quiet (bool) – Sets the verbosity of the logger to low and does not report queue position. Default is False.
reservation_arn (str | None) – The reservation ARN provided by Braket Direct to reserve exclusive usage for the device to run the quantum task on. Note: If you are creating tasks in a job that itself was created reservation ARN, those tasks do not need to be created with the reservation ARN. Default: None.

Returns:

AwsQuantumTask tracking the quantum task execution on the device.

Return type:

AwsQuantumTask

Note

The following arguments are typically defined via clients of Device.

task_specification
s3_destination_folder
shots
