Contributors list

This repository contains introductory materials on Quantum Machine Learning, as well as Python code demos using PennyLane, a cross-platform Python library for differentiable programming of quantum computers.

The content consists of four main areas:

Explore these materials on our website: https://pennylane.ai/qml. All tutorials are fully executable, and can be downloaded as Jupyter notebooks and Python scripts.

Contributing

You can contribute by submitting a demo via pull request implementing a recent quantum machine learning paper/result.

Adding demos

  • Demos are written in the form of an executable Python script. Any package listed in
    requirements.txt
    you can assume is available to be imported. Matplotlib plots will be automatically rendered and displayed on the QML website.

Note: try and keep execution time of your script to within 10 minutes.

  • If you would like to write the demo using a Jupyter notebook, you can convert the notebook to the required executable Python format by using this script.

  • All demos should have a file name beginning with

    tutorial_
    . The python files are saved in the
    demonstrations
    directory.
  • Restructured Text sections may be anywhere within the script by beginning the comment with 79 hashes (

    #
    ). These are useful for breaking up large code-blocks.
  • You may add figures within ReST comments by using the following syntax:

  ##############################################################################
  #.. figure:: ../demonstrations//image.png
  #    :align: center
  #    :width: 90%

where

 is a sub-directory with the name of
  your demo.

  • When complete, create a gallery link to your demo. This can be done by adding the snippet below to
    demos_getting-started.rst
    for introductory demos.
  .. customgalleryitem::
      :tooltip: An extended description of the demo
      :figure: demonstrations//thumbnail.png
      :description: :doc:`demos/pytorch_noise`

You should also add a link to your demo to the table of contents, by adding to the end of the

.. toctree::
in the appropriate file.

If you're unsure which file to put your demo in, choose the one you think is best, and we will work together to sort it during the review process.

  pip install black
  black -l 100 demo_new.py

and you are ready to submit a pull request!

If your demo uses the latest release of PennyLane, simply make your PR against the

master
branch. If you instead require the cutting-edge development versions of PennyLane or any relevant plugins, make your PR against the
dev
branch instead.

Tutorial guidelines

While you are free to be as creative as you like with your demo, there are a couple of guidelines to keep in mind.

  • Submissions should include your name (and optionally email) at the top under the title.

  • All contributions must be made under the Apache 2.0 license.

  • The title should be clear and concise, and if based on a paper it should be similar to the paper that is being implemented.

  • All demos should include a summary below the title. The summary should be 1-3 sentences that makes clear the goal and outcome of the demo, and links to any papers/resources used.

  • Code should be clearly commented and explained, either as a ReST-formatted comment or a standard Python comment.

  • Thumbnails should be legible, interesting, and unique --- but not too busy! Any included text should be minimal and legible.

  • If your content contains random variables/outputs, a fixed seed should be set for reproducibility.

  • All content must be original or free to reuse subject to license compatibility. For example, if you are implementing someone else's research, reach out first to recieve permission to reproduce exact figures. Otherwise, avoid direct screenshots from papers, and instead refer to figures in the paper within the text.

  • All submissions must pass code review before being merged into the repository.

Building

To build the website locally, simply run

make html
. The rendered HTML files will now be available in
_build/html
. Open
_build/html/index.html
to browse the built site locally.

Note that the above command may take some time, as all demos will be executed and built! Once built, only modified demos will be re-executed/re-built.

Alternatively, you may run

make html-norun
to build the website without executing demos, or build only a single demo using the following command:
sphinx-build -D sphinx_gallery_conf.filename_pattern=tutorial_QGAN\.py -b html . _build

where

tutorial_QGAN
should be replaced with the name of the demo to build.
