  DisCoPy (Distributional Compositional Python) is an open source toolbox for
computing with string diagrams and functors. In particular, the diagram data
structure allows to encode various kinds of quantum processes, with functors
for classical simulation and optimisation, as well as compilation and
evaluation on quantum hardware. This includes the ZX calculus and its many
variants, the parameterised circuits used in quantum machine learning, but also
linear optical quantum computing. We review the recent developments of the
library in this direction, making DisCoPy a toolbox for the quantum computer
scientist.
