quantum.cqmap#
Implements classical-quantum maps.
CQMap implements the classical-quantum processes of
Picturing Quantum Processes, Coecke and Kissinger (2018).
Objects are given by a quantum dimension Q (a.k.a. double wires)
and a classical dimension C (a.k.a. single wires).
Arrows are given by arrays of the appropriate shape, see CQMap.
For example, states of type Q are density matrices:
>>> from discopy.quantum import Ket, H
>>> (Ket(0) >> H).eval(mixed=True).round(1)
CQMap(dom=CQ(), cod=Q(Dim(2)), array=[0.5+0.j, 0.5+0.j, 0.5+0.j, 0.5+0.j])
