Local Optimality Does Not Compose: Invariant Simplices and the Complexity of Shared Probabilistic Automata
Yixin Zhao
Probabilistic models are often constructed separately for different test suites and then expected to share a single latent dynamical system. We study bounded-state shared realizati…

Entropic Rigidity in Quantum Memories: How Geometry and Algebra Control the Onset of Degeneracy Corrections
Yixin Zhao, Fei Yan
Maximum-probability (MP) decoding selects the most probable microscopic error, whereas degenerate maximum-likelihood (MLD) decoding includes the configurational entropy of an entir…
