Center node: "verification of linear optical quantum computing using quantum process calculus"
  Abstract: We explain the use of quantum process calculus to describe and analyse linear optical quantum#R##N#computing (LOQC). The main idea is to define two processes, one modelling a linear optical system#R##N#and the other expressing a specification, and prove that they are behaviourally equivalent. We extend#R##N#the theory of behavioural equivalence in the process calculus Communicating Quantum Processes#R##N#(CQP) to include multiple particles (namely photons) as information carriers, described by Fock#R##N#states or number states. We summarise the theory in this paper, including the crucial result that#R##N#equivalence is a congruence, meaning that it is preserved by embedding in any context. In previous#R##N#work, we have used quantum process calculus to model LOQC but without verifying models against#R##N#specifications. In this paper, for the first time, we are able to carry out verification. We illustrate this#R##N#approach by describing and verifying two models of an LOQC CNOT gate.
