OpenPulse is a concrete implementation of pulse grammar for cal and defcal body. It reuses the classical types and statements from openqasm3.

The package is structured similarly to openqasm3 with the modules:

• openpulse.ast: The AST nodes. Identical nodes from openqasm3.ast are re-exported.

• openpulse.parser: A parser similar to openqasm3.parser, but for OpenPulse.

• tests: A set of unit tests.

• No visitor module as openqasm3.visitor can be reused.

The OpenPulse grammar introduce the following:

• Pulse types: port, frame and waveform.
• Extension to OpenQASM 3 classical type to consume the pulse types.
