Heuristically a quantum Markov chain indexed by N is a state ϕ on ⊗NB (Ba matrix algebra) whose sequence of density matrices has a local structure (corresponding to the physical intuition that the interaction Hamiltonian is nearest neighbour). In [1] two classes of such chains were constructed: the Markov chains and the generalized Markov chains. In
