Azure Quantum Development Kit

Welcome to the Azure Quantum Development Kit!

This repository contains tooling for the Q# language, specifically:

compiler: core compiler logic and command-line tooling
fuzz: fuzz testing infrastructure
jupyterlab: JupyterLab extension
language_service: Q# language service and editor features
library: Q# standard library
npm: Q# npm package
pip: Q# Python pip package
playground: simple website for interacting with Q#
resource_estimator: Implementation for the Azure Quantum Resource Estimator
vscode: Visual Studio Code extension
wasm: The bindings and logic for the WebAssembly module
widgets: The Q# Jupyter widgets Python package

There are also the tutorials and samples in the ./katas and ./samples directories, respectively.

Code from this repository powers the Q# development experience on https://quantum.microsoft.com.

Building

To build this repository there are dependencies that need to be installed. These are:

Python (https://python.org)
Rust (https://www.rust-lang.org/tools/install)
Node.js (https://nodejs.org/)
wasm-pack (https://rustwasm.github.io/wasm-pack/installer/)
cmake (https://cmake.org/) and a C compiler

The build script will check these dependencies and their versions and fail if not met. (Or run python ./prereqs.py directly to check if the minimum required versions are installed).

To build, in the root directory run python ./build.py. By default this will run a release build of each project, including running tests and checks such as linting. Run with the --help option for detailed usage.

Playground

To run the "playground" locally, build the repository, then cd into the playground directory, and run npm start. This will launch a local web server and output the URL to the console; copy that URL and open it in a browser to use the playground. If you only want to build the functionality necessary to run the playground, you can use python .\build.py --wasm --npm --play.

Python

When building the Python packages (pip and jupyterlab), if the build script does not detect a current Python virtual environment, it will automatically create one under pip/.venv or jupyterlab/.venv. When developing locally, you can use these virtual environments to run the tests by running source .venv/bin/activate (Linux/MacOS) or .venv/Scripts/activate.bat (Windows).

Code editing

The easiest way to develop in this repo is to use VS Code. When you open the project root, by default VS Code will recommend you install the extensions listed in .vscode/extensions.json. These extensions provide language services for editing, as well as linters and formatters to ensure the code meets the requirements (which are checked by the build.py script and CI).

Some settings are recommended (but not enforced) to make development easier. These are in the .vscode/*.shared.json files. If the Workspace Config+ extension is installed, this will automatically apply these settings, as well as overrides from your own corresponding .vscode/*.local.json settings. If you don't install this extension, you can use these as a reference for editing your own .vscode/*.json settings files. (See the extension home page for more details).

Debugging

Besides the usual debugging tools for Rust code and web sites, there is some logging in the code that may be enabled to help troubleshoot. The qsc command-line compiler makes use of the Rust crate env_logger, which enables logging via environment variables, for example RUST_LOG=debug ./target/release/qsc ./samples/Grover.qs.
