Qubit transfer between photons at telecom and visible wavelengths in a slow-light atomic medium
A. Gogyan
We propose a method that enables efficient conversion of quantum information frequency between different regions of spectrum of light based on recently demonstrated strong parametr…
Entanglement-preserving frequency conversion in cold atoms
A. Gogyan, Yu. Malakyan
We propose a method that enables efficient frequency conversion of quantum information based on recently demonstrated strong parametric coupling between two single-photon pulses pr…
Creation of a Photonic Time-bin Qubit via Parametric Interaction of Photons in a Driven Resonant Medium
N. Sisakyan, Yu. Malakyan
A novel method of preparing a single photon in temporally-delocalized entangled modes is proposed and analyzed. We show that two single-photon pulses propagating in a driven nonabs…
Landau-Zener transition in quadratic-nonlinear two-state systems
A. M. Ishkhanyan
A comprehensive theory of the Landau-Zener transition in quadratic nonlinear two-state systems is developed. A compact analytic formula involving elementary functions only is deriv…
Generalized formula for the Landau-Zener transition in interacting Bose-Einstein condensates
A. M. Ishkhanyan
We present a rigorous analysis of the generalized Landau-Zener problem for the two-level interacting Bose-Einstein condensates. We show that the dynamics of the system is accuratel…
Quadratic-nonlinear Landau-Zener transition for association of an atomic Bose-Einstein condensate with inter-particle elastic interactions included
A. Ishkhanyan, R. Sokhoyan, K. -A. Suominen +2
We study the strong coupling limit of a quadratic-nonlinear Landau-Zener problem for coherent photo- and magneto-association of cold atoms taking into account the atom-atom, atom-m…
