Testing and Automating Quantum Compiler Workflows

RetroQ used retromorphic testing to reproduce known bugs and uncover new defects in PennyLane and Qiskit, including symbolic-parameter, commutation, self-adjointness, and crash failures. Agent-based migration of thirteen Qiskit benchmarks to CUDA-Q was fast but required corrective prompting and showed no consistently superior model, leaving correctness and generalization unresolved.
