Functor

class discopy.quantum.channel.Functor(ob, ar, dom=None, dtype=<class 'int'>)

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]).
