From Koszul-Complex Stabilizer Models to Superselection Profiles: Topological Rigidity and Nonsplit Extensions
Hao Song
Koszul-complex stabilizer models unify the toric-code hierarchy and bivariate-bicycle codes in one homological framework. To study translation-symmetry-enriched topological (SET) p…

Symmetry-enriched topological order and quasifractonic behavior in stabilizer codes
Siyu He, Hao Song
We study a broad class of qudit stabilizer codes, termed bivariate-bicycle (BB) codes, arising either as two-dimensional realizations of modulated gauge theories or…

Stabilizer Formalism for EAQECCs with Noise ebits
Ruihu Li, Guanmin Guo, Yang Liu +1
We introduce a stabilizer formalism for EAQECCs with noise ebits, using special subgroups of product groups of two Pauli groups. This formalism includes the two coding schemes,give…
