With the help of prior distributed entanglement as a \u201cquantum channel,\u201d quantum teleportation provides an intriguing means to faithfully transfer quantum states among distant locations without actual transmission of the physical carriers [Bennett CH, et al. (1993)\n                    <jats:italic>Phys Rev Lett<\/jats:italic>\n                    70(13):1895\u20131899]. Quantum memory enables controlled storage and retrieval of fast-flying photonic quantum bits with stationary matter systems, which is essential to achieve the scalability required for large-scale quantum networks. Combining these two capabilities, here we realize quantum teleportation between two remote atomic-ensemble quantum memory nodes, each composed of \u223c10\n                    <jats:sup>8<\/jats:sup>\n                    rubidium atoms and connected by a 150-m optical fiber. The spin wave state of one atomic ensemble is mapped to a propagating photon and subjected to Bell state measurements with another single photon that is entangled with the spin wave state of the other ensemble. Two-photon detection events herald the success of teleportation with an average fidelity of 88(7)%. Besides its fundamental interest as a teleportation between two remote macroscopic objects, our technique may be useful for quantum information transfer between different nodes in quantum networks and distributed quantum computing.\n                  <\/jats:p>","DOI":"10.1073\/pnas.1207329109","type":"journal-article","created":{"date-parts":[[2012,11,10]],"date-time":"2012-11-10T20:45:46Z","timestamp":1352580346000},"page":"20347-20351","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":104,"title":["Quantum teleportation between remote atomic-ensemble quantum memories"],"prefix":"10.1073","volume":"109","author":[{"given":"Xiao-Hui","family":"Bao","sequence":"first","affiliation":[{"name":"Hefei National Laboratory for Physical Sciences at Microscale and"},{"name":"Department of Modern Physics, University of Science and Technology of China, Hefei, Anhui 230026, China;"},{"name":"Physikalisches Institut der Universitaet Heidelberg, 69120 Heidelberg, Germany;
