Highly enhanced steady-state optomechanical entanglement via cross-Kerr nonlinearity
Entanglement [1, 2] is one of the most intriguing feature of quantum mechanics, having myriads of potential applications in quantum information and communication [3]. So far, preparation and manipulation of entanglement has been successfully demonstrated in microscopic systems, such as atoms , photons, ions [4–6] etc. However, the validity of entanglement in the macroscopic realm is still a deb...
متن کاملGenerating entanglement of photon-number states with coherent light via cross-Kerr nonlinearity
We 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. We study in detail the generation of the entangled states between two modes, and that among three modes. In addition to the Bell states...

متن کاملGeneration of continuous variable Einstein-Podolsky-Rosen entanglement via the Kerr nonlinearity in an optical fiber.
We report on the generation of a continuous variable Einstein-Podolsky-Rosen (EPR) entanglement using an optical fiber interferometer. The Kerr nonlinearity in the fiber is exploited for the generation of two independent squeezed beams. These interfere at a beam splitter and EPR entanglement is obtained between the output beams. The correlation of the amplitude (phase) quadratures is measured t...
متن کاملNonlocal Nondegenerate Optical Parametric Amplifier Based on Genuine Multipartite Entanglement
We propose a new scheme for realizing nonlocal nondegenerate optical parametric amplifier by means of genuine four-mode entanglement. The nondegenerate optical parametric amplifier is regarded as a unitary transformation from two input fields to two outputs. Two inputs and two outputs are located at the remote stations respectively. Employing off-line four-mode entanglement, homodyne detection,...
