Enhancing optical delay using cross-Kerr nonlinearity in Rydberg atoms
Applied Optics, 2020A scheme to enhance the optical delay in Rydberg atoms is proposed. In the linear case, the optical delay in a four-level system can be significantly enhanced compared to that of the three-level system. However, the width of the transparent window will decrease with an increase in the optical delay.

Generation of an arbitrary logic W state with cross-Kerr nonlinearities
Laser Physics Letters, 2020Abstract Environmental noise is a big obstacle in quantum communication and computation. Quantum error code (QEC) technology can resist the photon transmission loss and decoherence error caused by the environmental noise and has great application potential in future quantum communication and computation fields. The generation of logic

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.
