Enhance your quantum development

Flexible quantum programming

Compose quantum algorithms interchangeably across Q#, Python, OpenQASM, Qiskit, and Cirq. Then run code anywhere with QIR support.

AI-powered quantum development

Enhance your learning, research, and development with agentic AI tools that work inside the editor across multiple quantum languages.

Decreased time to solution

Design, test, and refine quantum applications—and receive results within VS Code—before submitting jobs to simulators or real quantum hardware.

New in QDK

Microsoft AI-Powered Learning in QDK

The Microsoft AI-Powered learning experience brings interactive quantum computing lessons, hands-on exercises, and GitHub Copilot assistance directly into VS Code, with a curated progression from foundational concepts to complex quantum algorithms and instant, personalized hints whenever you need guidance.

The power is in learning by doing. As you write code in QDK and complete exercises, you build genuine intuition about quantum concepts through direct practice. Theory, implementation, and execution, all in one workspace.
