Abstract Quantum computing systems promise to increase the capabilities for solving problems which classical computers cannot handle adequately, such as integers factorization. In this paper, we present a formal modeling and verification approach for optical quantum circuits, where we build a rich library of optical quantum gates and develop a proof strategy in higher-order logic to reason about optical quantum circuits automatically. The constructed library contains a variety of quantum gates ranging from 1-qubit to 3-qubit gates that are sufficient to model most existing quantum circuits. As real world applications, we present the formal analysis of several quantum circuits including quantum full adders and the Grover’s oracle circuits, for which we have proved the behavioral correctness and calculated the operational success rate, which has never been provided in the literature. We show through several case studies the efficiency of the proposed framework in terms of the scalability and modularity.
