  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](https://strawberryfields.ai/photonics/hardware/index.html).



* [High-level functions](https://strawberryfields.ai/photonics/applications.html) 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](https://strawberryfields.ai/photonics/demonstrations.html#optimization-and-machine-learning)

  your quantum programs with our end-to-end differentiable TensorFlow backend.



## Installation



Strawberry Fields requires Python version 3.7, 3.8, 3.9, or 3.10. Installation of Strawberry Fields, as

well as all dependencies, can be done using pip:



```console

pip install strawberryfields

```



## Getting started



To get started with writing your own Strawberry Fields code, begin with our [photonic circuit

quickstart guides](https://strawberryfields.readthedocs.io/en/stable/introduction/introduction.html),

before exploring our many [tutorials](https://strawberryfields.ai/photonics/demonstrations.html) and

[applications](https://strawberryfields.ai/photonics/applications.html).





  




Next, read more about using Strawberry Fields with

[photonic hardware](https://strawberryfields.ai/photonics/hardware/index.html), including code

demonstrations and an overview of Xanadu's quantum photonic hardware.



Developers can head to the

[development guide](https://strawberryfields.readthedocs.io/en/stable/development/development_guide.html)

to see how they can contribute to Strawberry Fields.
