OpenQASM is an imperative intermediate representation and assembly language for describing quantum circuits, supporting universal quantum computing, measurement-based models, and near-term experiments. This repository hosts the language specification (currently version 3.1), examples, a reference grammar, and tooling for the OpenQASM IR.

Use cases

• write quantum circuits in a standard assembly language
• parse OpenQASM 3 programs with a reference grammar
• define an intermediate representation for quantum compilers
• learn the OpenQASM 3.1 language specification
• share quantum circuits between quantum SDKs and hardware vendors
• describe pulse-level calibrations and timing for quantum hardware

When to choose

• you need a vendor-neutral format to exchange quantum circuits between tools
• you are building a quantum compiler, simulator, or hardware backend that consumes circuit descriptions
• you want the authoritative spec, grammar, and examples for OpenQASM 3

When to avoid

• you need a high-level quantum SDK with simulators and transpilers rather than a language spec (use Qiskit, Cirq, or PennyLane)
• you want a runnable quantum simulator out of the box
• you target only OpenQASM 2.0 workflows without needing version 3 features
