Phys. Rev. Lett. 78, 3221–3224 (1997)Quantum State Transfer and Entanglement Distribution among Distant Nodes in a Quantum NetworkReceived 12 November 1996; published in the issue dated 21 April 1997 We propose a scheme to utilize photons for ideal quantum transmission between atoms located at spatially separated nodes of a quantum network. The transmission protocol employs special laser pulses that excite an atom inside an optical cavity at the sending node so that its state is mapped into a time-symmetric photon wave packet that will enter a cavity at the receiving node and be absorbed by an atom there with unit probability. Implementation of our scheme would enable reliable transfer or sharing of entanglement among spatially distant atoms. © 1997 The American Physical Society URL:
