In a joint effort, researchers from the Humboldt-Universität (Berlin), the Max Born Institute (Berlin) and the University of Central Florida (U.S.) have revealed the necessary conditions for the robust transport of entangled states of two-photon light in photonic topological insulators, paving the way the toward noise-resistant transport of quantum information. The results have appeared in Nature Communications.
