We apply the recent graphical framework of ''quantum lego'' to XP stabilizer codes where the stabilizer group is generally non-abelian. We show that the idea of operator matching continues to hold for such codes and is sufficient for generating all t

Composite Quantum Phases in Non-Hermitian Systems

Autor: Guo, Yuchen, Shen, Ruohan, Yang, Shuo

Publikováno v: Phys. Rev. Research 5, 033181 (2023)

Non-Hermitian systems have attracted considerable interest in recent years owing to their unique topological properties that are absent in Hermitian systems. While such properties have been thoroughly characterized in free fermion models, they remain

Construction of Non-Hermitian Parent Hamiltonian from Matrix Product States

Autor: Shen, Ruohan, Guo, Yuchen, Yang, Shuo

Publikováno v: Phys. Rev. Lett. 130, 220401 (2023)

There are various research strategies used for non-Hermitian systems, which typically involve introducing non-Hermitian terms to pre-existing Hermitian Hamiltonians. It can be challenging to directly design non-Hermitian many-body models that exhibit
