Functor# class discopy.quantum.channel.Functor(ob, ar, dom=None, dtype=<class 'int'>)[source]# Bases: Functor A channel functor is a tensor functor into classical-quantum channels. Parameters: ob (dict[cat.Ob, CQ]) – The object mapping. ar (dict[cat.Box, array]) – The arrow mapping. dom (T) – The domain of the functor. dtype (type) – The datatype for the codomain Category(CQ, Channel[dtype]).
