Two photons can be entangled in their mode structure. This has the advantage that more information can be encoded than by using polarization. Wolfgang Löffler and colleagues from the Quantum Optics group were able to demonstrate that this so-called 'spatial' entanglement can survive fiber transport. Credit: Wolfgang Löffler.

"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."
