摘要：

We present a quantum teleportation experiment in the quantum relay configuration using the installed telecommunication network of Swisscom. In this experiment, the Bell-state measurement occurs well after the entanglement has been distributed, at a point where the photon upon which data are teleported is already far away, and the entangled qubits are photons created from a different crystal and laser pulse than the teleported qubit. A raw fidelity of 0.93 +/- 0.04 has been achieved using a heralded single-photon source. (c) 2007 Optical Society of America.
