Topological protection versus degree of entanglement of two-photon light in photonic topological insulators

Researchers from HU, MBI, and the University of Central Florida (USA) have identified criteria for robust transport:

Originally discovered in condensed matter systems, topological insulators are two-dimensional materials that support scattering-free (uni-directional) transport along their edges, even in the presence of defects and disorder....
