Entangled state transport between an atom and a photon has been conducted over a distance of 12 miles

A new record in the transport of an entanglement state between an atom and a photon on an optical fiber was achieved by physicists at the Ludwig-Maximilians-Universitaet (LMU) in Munich. With the help of colleagues from the University of Saarland, the researchers were able to successfully transport this state over a distance of 12 miles. […]
