Bisimulation for quantum processes

Yuan FengAssociate ProfessorCentre for Quantum Computation and Intelligent Systems, University of Technology, Sydney, Australia

We introduce a novel notion of probabilistic bisimulation for quantum processes and prove that it is congruent with respect to various process algebra combinators including parallel composition even when both classical and quantum communications are present. We also establish some basic algebraic laws for this bisimulation. In particular, we prove uniqueness of the solutions to recursive equations of quantum processes, which provides a powerful proof technique for verifying complex quantum protocols.

This is a joint work with R. Duan and M. Ying, published at POPL 2011.
