Cocycle Actions on Hidden Quantum Markov Models: Symmetry Protection and Topological Order

Abdessatar Souissi, Abdessatar Barhoumi

We develop a symmetry action framework for hidden quantum Markov models (HQMMs) tailored to one-dimensional quantum spin systems and symmetry-protected topological (SPT) phases. In…

Causal Architecture in Hidden Quantum Markov Models

Abdessatar Souissi, Abdessatar Barhoumi

We introduce a class of causal hidden quantum Markov models (cHQMMs) that reverse the usual order of hidden updates and emissions compared to conventional HQMMs. Using a simple qub…
