Query: Model Checking Quantum Systems --- A Survey   This article discusses the essential difficulties in developing
model-checking techniques for quantum systems that are never present in model
checking classical systems. It further reviews some early researches on
checking quantum communication protocols as well as a new line of researches
pursued by the authors and their collaborators on checking general quantum
systems, applicable to both physical systems and quantum programs.
