Create and submit an example OpenQASM 3.0 quantum task
You can use the Amazon Braket Python SDK, Boto3, or the AWS CLI to submit OpenQASM 3.0 quantum tasks to an Amazon Braket device.
In this section:
An example OpenQASM 3.0 program
To create a OpenQASM 3.0 task, you can start with a simple OpenQASM 3.0 program
(ghz.qasm) that prepares a GHZ state
// ghz.qasm // Prepare a GHZ state OPENQASM 3; qubit[3] q; bit[3] c; h q[0]; cnot q[0], q[1]; cnot q[1], q[2]; c = measure q;
Use the Python SDK to create OpenQASM 3.0 quantum tasks
You can use the Amazon Braket Python SDK
with open("ghz.qasm", "r") as ghz: ghz_qasm_string = ghz.read() # import the device module from braket.aws import AwsDevice # choose the Rigetti device device = AwsDevice("arn:aws:braket:us-west-1::device/qpu/rigetti/Aspen-M-3") from braket.ir.openqasm import Program program = Program(source=ghz_qasm_string) my_task = device.run(program) # You can also specify an optional s3 bucket location and number of shots, # if you so choose, when running the program s3_location = ("amazon-braket-my-bucket", "openqasm-tasks") my_task = device.run( program, s3_location, shots=100, )
Use Boto3 to create OpenQASM 3.0 quantum tasks
You can also use AWS Python SDK for Braket (Boto3)
import boto3 import json my_bucket = "amazon-braket-my-bucket" s3_prefix = "openqasm-tasks" with open("ghz.qasm") as f: source = f.read() action = { "braketSchemaHeader": { "name": "braket.ir.openqasm.program", "version": "1" }, "source": source } device_parameters = {} device_arn = "arn:aws:braket:us-west-1::device/qpu/rigetti/Aspen-M-3" shots = 100 braket_client = boto3.client('braket', region_name='us-west-1') rsp = braket_client.create_quantum_task( action=json.dumps( action ), deviceParameters=json.dumps( device_parameters ), deviceArn=device_arn, shots=shots, outputS3Bucket=my_bucket, outputS3KeyPrefix=s3_prefix, )
Use the AWS CLI to create OpenQASM 3.0 tasks
The AWS Command Line Interface (CLI)
aws braket create-quantum-task \ --region "us-west-1" \ --device-arn "arn:aws:braket:us-west-1::device/qpu/rigetti/Aspen-M-3" \ --shots 100 \ --output-s3-bucket "amazon-braket-my-bucket" \ --output-s3-key-prefix "openqasm-tasks" \ --action '{ "braketSchemaHeader": { "name": "braket.ir.openqasm.program", "version": "1" }, "source": $(cat ghz.qasm) }'
