Enhanced photon-phonon cross-Kerr nonlinearity with two-photon driving
Optics Letters, 2018We propose a scheme to significantly enhance the cross-Kerr (CK) nonlinearity between photons and phonons in a quadratically coupled optomechanical system (OMS) with two-photon driving. This CK nonlinear enhancement originates from the parametric-driving-induced squeezing and the underlying nonlinear optomechanical interaction.

Decoherence-induced cross-Kerr nonlinearity for quantum entanglement
Laser Physics LettersAbstract In this paper, we show that the cross-Kerr nonlinearity is induced by the ground-state decoherence in a Λ system even under the exact one- and two-photon resonance conditions, which is attributed to the fact that the dark-state resonance is broken slightly.

Entanglement generation with coherent states using cross-Kerr nonlinearity
Journal of the Optical Society of America B, 2013We propose methods for generating Bell-type entangled coherent states for quantum information processing. The protocols are completed using linear optical elements, single-photon detectors, and cross-Kerr nonlinearity. We investigate the decoherence effect on our protocols; photon loss is found to affect only the probability, not the fidelity, of the ...

Entanglement generation with coherent light via cross-Kerr-nonlinearity
SPIE Proceedings, 2007We propose a scheme for generating entangled states of light fields. This scheme only requires the cross-Kerr nonlinear interaction between coherent light-beams, followed by a homodyne detection. Therefore, this scheme is within the reach of current technology.

Nonlinear cross-Kerr quasiclassical dynamics
2014We study the quasiclassical dynamics of the cross-Kerr effect. In this approximation, the typical periodical revivals of the decorrelation between the two polarization modes disappear and remain entangled. By mapping the dynamics onto the Poincaré space, we find simple conditions for polarization squeezing.

Decoherence in cross-Kerr nonlinearity based on electromagnetically induced transparency
The European Physical Journal D, 2014The effects of decoherence due to dephasing and incoherent population exchange on the cross-Kerr nonlinearity are investigated. In the linear optical behavior, the incoherent population exchange suppresses the linear resonance such as the Autler-Townes absorption and the electromagnetically induced transparency in the same manner as the dephasing ...
