Transporting spatially entangled photons through an optical fiber

(PhysOrg.com) — “Spatially entangled photons is a hot topic in quantum information science, and optical fibers are the cornerstone of our communication society,” Wolfgang Loffler tells PhysOrg.com. “So far, though, no one that we know of has demonstrated that you can use a fiber to transport a photon entangled in its spatial degree of freedom.”
