Schnakenberg's network theory revisited: from the minEP 
principle to spin networks#
In a celebrated paper, Julian Schnakenberg proposed a general 
theory of fluxes of information and conservation laws on a 
network, identifying the macroscopic external observables which 
keep a system out of equilibrium. In this talk we show that his 
observables are indeed the correct constraints to be imposed to 
Prigogine's minimum entropy production principle. Speculation 
about the possible quantum version of Schnakenberg's theory 
leads to the identification of SU(2) spin networks as an useful 
mathematical instrument -the very same spin networks that have 
been used by Rasetti in a quantum information perspective to 
engineer a model of a quantum Turing machine.
