This work presents tweedledum-an extensible open-source library aiming at narrowing the gap between high-level algorithms and physical devices by enhancing the expressive power of existing frameworks. For example, it allows designers to insert classical logic (defined at a high abstraction level, e.g., a Python function) directly into quantum circuits. We describe its design principles, concrete implementation, and, in particular, the library's core: An intuitive and flexible intermediate representation (IR) that supports different abstraction levels across the same circuit structure.
