Phys. Rev. A 68, 023804 (2003) [7 pages]Nonperturbative quantum solutions to resonant four-wave mixing of two single-photon wave packetsReceived 10 April 2003; published 13 August 2003 We analyze both analytically and numerically the resonant four-wave mixing of two co-propagating single-photon wave packets. We present analytic expressions for the two-photon wave function, and show that quantum solutions exist which display a shape-preserving oscillatory exchange of excitations between the modes. Potential applications including quantum-information processing are discussed. © 2003 The American Physical Society URL:
