ENTANGLEMENT CONCENTRATION WITH CROSS-KERR NONLINEARITY
International Journal of Modern Physics B, 2014We propose a protocol for realizing two entanglement concentration scheme with cross-Kerr nonlinearity and double cross-phase modulation method. In our protocols, two remote parties do not require the accurate information of the less entangled state and the double cross-phase modulation is introduced to overcome the errors caused by the imperfect Kerr

Nearly deterministic controlled-NOT gate with weak cross-Kerr nonlinearities
Quantum Information and Computation, 2012On the basis of the probe coherent state and weak cross-Kerr nonlinearities, we present a scheme of a nearly deterministic Controlled-NOT gate. In this construction, feed-forward methods, quantum nondemolition detectors and several optical elements are applied. It is a potentially practical quantum gate with certain features.

Polarization-entanglement purification and concentration using cross-Kerr nonlinearity
Quantum Information and Computation, 2011We present an entanglement purification protocol and an entanglement concentration protocol in this paper, resorting to cross-Kerr nonlinearities and interference of two coherent beams. Our purification protocol can be used to purify photon pairs not only from an ideal entangled source but also from a parametric down-conversion source by the ...

Complete Quantum Teleportation with a Crossed-Kerr Nonlinearity
2006We show how perfect Bell-state discrimination and complete quantum teleportation of the polarization state of a photon can he implemented employing a cross-Kerr medium. We show that, using the recently demonstrated ultraslow light propagation in coherent atomic media, the proposal can be realized with presently available technology.

Photon blockade with cross-Kerr nonlinearity in superconducting circuits
Laser Physics Letters, 2018Abstract We theoretically investigate the photon statistical properties of a weakly-driven circuit quantum electrodynamic system with a cross-Kerr nonlinearity, which is built from two coupled transmon qubits through a superconducting quantum interference device (SQUID).

Bypassing dynamic reciprocity via a chiral cross-Kerr nonlinearity
Conference on Lasers and Electro-Optics, 2022The optical Kerr nonlinearity can't be used to achieve on-chip optical nonreciprocity because of dynamic reciprocity. Here, we propose a chiral cross-Kerr nonlinearity to bypass dynamic reciprocity and to achieve all-optical nonreciprocity on a chip.

Dicke state generation using cross-Kerr nonlinearity
Journal of Modern Optics, 2011In this paper, we propose two ways of Dicke state generation using single photons and weak coherent pulse resorting to Kerr nonlinearities. By interference of two coherent beams, the Dicke state are realized in polarization and photon number degrees of freedom.

Cross-Kerr nonlinearities in an optically dressed periodic medium
Physica Scripta, 2011Cross-Kerr nonlinearities are analyzed for two light beams propagating in an atomic medium in the tripod configuration, dressed by a strong standing-wave laser field that induces periodic optical properties. The reflection and transmission spectra as well as the phases of both the reflected and transmitted components of the two beams are analyzed ...
