OpenQASM 2 Tools for Qiskit

This project is an exploratory package for interoperating between Qiskit and OpenQASM 2. It currently offers the functions load() and loads(), which are significantly faster (often 10x or more) drop-in replacements for the Qiskit methods QuantumCircuit.from_qasm_file and QuantumCircuit.from_qasm_str respectively. The core of these functions is a custom parser written in Rust.

In the future, this package may add exploratory new methods to replace QuantumCircuit.qasm as well. There are various historical inefficiencies and architectural difficulties in the current implementation, and this package provides a testbed free of Qiskit’s deprecation policy to help develop a new interface. The experience may go on to inform changes to Qiskit’s OpenQASM 3 support as well.
