QuSema: Detecting Silent Bugs in Quantum Libraries via Quantum-knowledge-enhanced Agents

Key points

• Quantum libraries are now critical infrastructure for quantum algorithm development, yet their correctness remains difficult to test.1
• QuSema uses constraints from quantum semantics and documentation as a source-level semantic oracle to assess whether implementation logic can produce invalid outputs from valid inputs.1
• Guided by quantum-domain reasoning, QuSema turns high-level behavioral mismatches into concrete, user-triggerable bug reports, enabling it to uncover non-crash defects.1
• We implement QuSema for Qiskit and PennyLane.1
