Center node: "reasoning about parallel quantum programs"
  Abstract: We initiate the study of parallel quantum programming by defining the operational and denotational semantics of parallel quantum programs. The technical contributions of this paper include: (1) find a series of useful proof rules for reasoning about correctness of parallel quantum programs; and (2) prove a strong soundness theorem of these proof rules showing that partial correctness is well maintained at each step of transitions in the operational semantics of a parallel quantum program. This is achieved by partially overcoming the following conceptual challenges that are never present in classical parallel programming: (i) the intertwining of nondeterminism caused by quantum measurements and introduced by parallelism; (ii) entanglement between component quantum programs; and (iii) combining quantum predicates in the overlap of state Hilbert spaces of component quantum programs with shared variables. It seems that a full solution to these challenges and developing a (relatively) complete proof system for parallel quantum programs are still far beyond the current reach.
