    Quantum Entanglement Sent Over 50 Km of Optical Fiber

    Article obtained from Photonics RSS Feed.

    A team from the University of Innsbruck and the Institute of Quantum Optics and Quantum Information of the Austrian Academy of Sciences has achieved what could be a record for the transfer of quantum entanglement between matter (a trapped ion) and light (a photon). The team sent quantum information over a distance of 50 km using fiber optic cables. “This is two orders of magnitude further than was previously possible and is a practical distance to start building intercity quantum networks,” lead researcher Ben Lanyon said.

    The researchers began by trapping a calcium atom in an ion trap. Using lasers, they wrote a quantum state onto the ion while exciting it to emit a photon, in which quantum information was stored. The…
