# Microsoft Quantum Development Kit (QDK)

This extension brings rich language support for Q# and OpenQASM to VS Code. Develop, build, and run your quantum code from VS Code either locally on simulators, or by submitting a job to Azure Quantum.

You can also try out this extension in VS Code for Web at [vscode.dev/quantum/playground](https://vscode.dev/quantum/playground/).

## Features

The QDK extension currently supports:

- Syntax highlighting and syntax features (e.g. brace matching) for Q# and OpenQASM
- Editing features such as go-to-definition, suggestions and signature help for Q# and OpenQASM
- Error checking in Q# and OpenQASM source files
- Local quantum simulation, including support for Pauli noise and qubit loss
- Breakpoint debugging for Q# and OpenQASM
- Code samples for Q# and OpenQASM demonstrating well known algorithms
- Circuit diagram visualization and editing
- Q# cell support in Jupyter notebooks. The extension will detect `%%qsharp` magic cells and automatically update the cell language to Q#
- Integration with Azure Quantum for job submission to quantum hardware providers
