A holographic framework links quantum channel behavior to topology

Tsung-Cheng Lu of the University of Maryland, Yu-Jie Liu of the Massachusetts Institute of Technology, Sarang Gopalakrishnan of Princeton University, and Yizhi You of Northeastern University have established a framework linking the behavior of quantum channels to a higher-dimensional system. Their work demonstrates that a d-dimensional quantum channel can be mapped to the boundary of a (d+1)-dimensional wavefunction, revealing how strong-to-weak spontaneous symmetry breaking arises from anyon condensation on the boundary of a topological order. Researchers utilized isometric tensor network states to identify a quantum channel’s…
