Q# Quantum Programming Language

Q# is Microsoft's open-source, hardware-agnostic quantum programming language. The Modern QDK compiler is written in Rust, ships as a VS Code extension and Python package, and powers quantum.microsoft.com. Q# expresses programs as classical control-flow that operates on qubits without modeling the quantum state directly, and targets every Azure Quantum provider plus the Resource Estimator.
