Abstract:

Abstract: We address the entanglement transfer from a bipartite continuous-variable(CV) system to apair of localized discrete systems. The dynamics behavior can be implemented by twotwo-level atoms flying through spatially separated identical cavities where two quantizedmodes are injected. We assume each CV mode couples to one atom via the resonantJaynes-Cummings interaction. The CV systems are initially prepared in a two-modeanti-correlated SU(2) coherent state, while with the initial atomic states of the cases:|g⟩1|g⟩2, |e⟩1|e⟩2 and |g⟩1|e⟩2, respectively. We find that the entanglement transfer forsingle-photon excitation case is more efficient than that for multi-photon excitationcase. Under same conditions, we also note that the entanglement transfer is more efficientfor SU(2) coherent state than for twin-bean (TWB) and pair-coherent (TMC) state. Besides,we show that, for a given total photon number of the initial SU(2) coherent state, theefficiency of entanglement transfer depends upon the distribution of photons in the two CVmodes. We also consider the influences of the dissipation and the white noise on theentanglement transfer.
