Teleportation to a Solid-State Quantum Memory

The Gisin group has done it again! This time, they have managed to teleport a quantum state via photons and into a quantum memory in a form of a doped crystal.

Today, Felix Bussières at the University of Geneva in Switzerland and a few pals say they’ve taken an important step towards this. These guys have teleported quantum information to a crystal doped with rare-earth ions—a kind of quantum memory. But crucially they’ve done it for the first time over the kind of ordinary optical fiber that telecommunications that are in use all over the world.
