Introducing QPMC:

Yuan Feng, Ernst Moritz Hahn, Andrea Turrini, Lijun Zhang, QPMC: A Model Checker for Quantum Programs and Protocols, in Formal Methods. FM 2015, Lecture Notes in Computer Science 9109, Springer (2015) [doi:10.1007/978-3-319-19249-9_17]

“In practice, however, security analysis of quantum cryptographic protocols is notoriously difficult; for example, the manual proof of BB84 in [15] contains about 50 pages. It is hard to imagine such an analysis being carried out for more sophisticated quantum protocols. Thus, techniques for automated or semi-automated verification of these protocols will be indispensable.”

Background and review:

Mingsheng Ying, Yuan Feng, Model Checking Quantum Systems — A Survey [arXiv:1807.09466]

“But to check whether a quantum system satisfies a certain property at a time point, one has to perform a quantum. measurement on the system, which can change the state of the system. This makes studies of the long-term behaviours of quantum systems much harder than that of classical system.”

“The state spaces of the classical systems that model-checking algorithms can be applied to are usually finite or countably infinite. However, the state spaces of quantum systems are inherently continuous even when they are finite-dimensional. In order to develop algorithms for model-checking quantum systems, we have to exploit some deep mathematical properties of the systems so that it suffices to examine only a finite number of (or at most countably infinitely many) representative elements, e.g. those in an orthonormal basis, of their state spaces.”
