Strawberry Fields

Travis Codecov coverage CodeFactor Grade Read the Docs PyPI PyPI - Python Version

Strawberry Fields is a full-stack Python library for designing, simulating, and optimizing continuous variable quantum optical circuits.


  • An open-source software architecture for photonic quantum computing
  • Execute algorithms on photonic quantum computing chips via the Xanadu Quantum Cloud
  • Includes high-level functions for solving practical problems including graph and network optimization, machine learning and chemistry
  • Includes quantum simulators implemented using NumPy and TensorFlow—with built-in quantum compilation
  • Powers the Strawberry Fields Interactive web app, which allows anyone to run a quantum computing simulation via drag and drop


Strawberry Fields requires Python version 3.6, 3.7, or 3.8. Installation of Strawberry Fields, as well as all dependencies, can be done using pip:

pip install strawberryfields

Getting started

To see Strawberry Fields in action immediately, try out our Strawberry Fields Interactive web application. Prepare your initial states, drag and drop gates, and watch your simulation run in real time right in your web browser.

For getting started with writing your own Strawberry Fields code, follow the installation page to get Strawberry Fields up and running, then jump over to the tutorials to see what you can do.

Users interested in applications of photonic quantum computers should check out the Graphs and Networks, Machine Learning and Chemistry pages. Those wanting to dig deeper into the design of circuits can head to the quantum circuits page.

Developers can head to the development guide to see how they can contribute to Strawberry Fields.
