🌐🦀 OpenQASM 3 Parser

openqasm3_parser provides a compiler front end for OpenQASM 3 language (OQ3).

In this document, this parser is referred to as openqasm3_parser.

Differences with the OpenQASM reference parser are

• The parser in openqasm3_parser is much more performant. A crude test with large source files showed parse time reduced by a factor of 80.
• openqasm3_parser performs semantic analysis.
