Open Bisimulation for Quantum Processes

摘要

Quantum processes describe concurrent communicating systems that may involve quantum information. We propose a notion of open bisimulation for quantum processes and show that it provides both a sound and complete proof methodology for a natural extensional behavioural equivalence between quantum processes. We also give a modal characterisation of the behavioural equivalence, by extending the Hennessy-Milner logic to a quantum setting.
