Phys. Rev. A 70, 063809 (2004) [16 pages]Photon-echo quantum memory with efficient multipulse readingsReceived 8 May 2003; revised 8 July 2004; published 15 December 2004 We present a photon-echo quantum memory technique for manipulating quantum states of photons interacting with an atomic gas medium. The technique offers vast potential for the complete nonlocal-in-time multipulse reconstruction of a stored light as a superposition of echo fields, irradiated from the medium at different moments of time. Using this technique the dynamic control of quantum states is effectively possible by simply varying the laser parameters. © 2004 The American Physical Society URL:
