Locally Purified Density Operators for Symmetry-Protected Topological Phases in Mixed States
We propose a tensor network approach known as the locally purified density operator (LPDO) to investigate the classification and characterization of symmetry-protected topological phases in open quantum systems. We extend the concept of injectivity, originally associated with matrix product states a...
