Quantum teleportation is the faithful transfer of quantum states between
systems, relying on the prior establishment of entanglement and using only
classical communication during the transmission. We report teleportation of
quantum information between atomic quantum memories separated by about 1 meter.
A quantum bit stored in a single trapped ytterbium ion (Yb+) is teleported to a
second Yb+ atom with an average fidelity of 90% over a replete set of states.
The teleportation protocol is based on the heralded entanglement of the atoms
through interference and detection of photons emitted from each atom and guided
through optical fibers. This scheme may be used for scalable quantum
computation and quantum communication.Comment: 5 pages, 4 figure
