Topological squashed entanglement: Nonlocal order parameter for one-dimensional topological superconductors
Identifying entanglement-based order parameters characterizing topological systems, in particular topological superconductors and topological insulators, has remained a major challenge for the physics of quantum matter in the last two decades. Here we show that the end-to-end, long-distance, biparti...
