Amazon Braket Strawberry Fields Plugin

As of 06/02/2023, Xanadu's Borealis device is no longer available on Amazon Braket. Therefore, information on this page may be outdated. Please visit the Xanadu Strawberry Fields page for additional information: https://www.xanadu.ai/products/strawberry-fields

This plugin provides a BraketEngine class for running photonic quantum circuits created in Strawberry Fields on the Amazon Braket service.

The Amazon Braket Python SDK is an open source library that provides a framework to interact with quantum computing hardware devices and simulators through Amazon Braket.

Strawberry Fields is an open source library for writing and running programs for photonic quantum computers.

The plugin documentation can be found here: https://amazon-braket-strawberryfields-plugin-python.readthedocs.io/en/latest/.

Features

This plugin provides the classes BraketEngine for submitting photonic circuits to Amazon Braket and BraketJob for tracking the status of the Braket task.

BraketEngine and BraketJob have the same interfaces as RemoteEngine in Strawberry Fields and Job in the Xanadu Cloud Client, respectively, and can be used as drop-in replacements:

from braket.strawberryfields_plugin import BraketEngine

eng = BraketEngine("arn:aws:braket:us-east-1::device/qpu/xanadu/Borealis")
result = eng.run(prog, shots=1000)  # Synchronous, returns sf.Result
job = eng.run_async(prog, shots=1000)  # Asychronous, returns BraketJob
print(job.status)
