AKLT State is Indeed the Observation Process of a causal Hidden quantum Markov Model

Abdessatar Souissi, Amenallah Andolsi

We present a rigorous formulation of the spin-1 Affleck--Kennedy--Lieb--Tasaki (AKLT) state within the framework of hidden quantum Markov models (HQMMs). We show that the AKLT grou…
