Nonperturbative quantum solutions to resonant four-wave mixing of two single-photon wave packets

Abstract: 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 soliton-type quantum solutions exist which display a shape-preserving oscillatory exchange of excitations between the modes. Potential applications including quantum information processing are discussed.

“…Bragg scattering in nonlinear fibers or FWM in atomic gases) as demonstrated for weak coherent fields [18,19] and heralded single photons [20,21]. We mention that the use of atomic ensembles as nonlinear media for single-photon frequency conversion is also being discussed [22,23], and has been experimentally demonstrated [21]. This latter approach offers a smaller bandwidth compared with nonlinear crystals, but also a better perspective for achieving coherent control [24].…”
