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

Features

• Execute photonic quantum algorithms directly on Xanadu's next-generation quantum hardware.

• High-level functions for solving practical problems including graph and network optimization, machine learning, and chemistry.

• Includes a suite of world-class simulators—based on cutting-edge algorithms—to compile and simulate photonic algorithms.

• Train and optimize your quantum programs with our end-to-end differentiable TensorFlow backend.

Installation

Strawberry Fields requires Python version 3.8, 3.9, or 3.10. Installation of Strawberry Fields, as well as all dependencies, can be done using pip:

pip install strawberryfields

Getting started

To get started with writing your own Strawberry Fields code, begin with our photonic circuit quickstart guides, before exploring our many tutorials and applications.

Next, read more about using Strawberry Fields with photonic hardware, including code demonstrations and an overview of Xanadu's quantum photonic hardware.
