Abstract

We propose an optical scheme for the generation of the cluster-type entangled coherent states in free travelling optical fields via cross-Kerr nonlinearity. The required resources for the generation are coherent state source, beam splitters, photodetectors, and Kerr media. We also discuss the implementation of the Hadamard gate operation for coherent states and the homodyne detection.

Generation of Four-Mode Cluster-Type Entangled Coherent States in Free-Traveling Optical Fields

Dai-Guo He, Yuli Dong, Fang Jian-Xing +2 more

In this paper, we propose an optical scheme to generate four-mode cluster-type entangled coherent states (ECSs) in free traveling optical fields by using two single-photon sources, coherent state sources, beam splitters, photodetectors, cross-Kerr media, and phase shifters. And the success probability of the states preparation is calculated. At last we discuss the experimental feasibility of such proposal.

Generation of three-mode W-type entangled coherent states in free-travelling optical fields

郭裕 郭裕, 匡乐满, Guo Yu

We propose a scheme for generation of three-mode W-type entangled coherent states (ECSs) in free-travelling optical fields by using a single-photon source, coherent state sources, beam splitters, photodetectors, and three-mode cross-Kerr media. The scheme consists of a Mach-Zehnder interferometer (MZI) in which each arm contains a cross-Kerr medium. We calculate the success probability of the generated W-type ECSs, and the total success probability is unity under the ideal conditions.

Generation of four-photon polarization-entangled cluster states via cross-Kerr nonlinearity

Lai Bo-Hui, Du Gang, Yu Ya-Fei +3 more

We propose a scheme for generating four-photon polarization-entangled cluster states based on the cross-Kerr nonlinear interaction between field-modes. Compared with other schemes, our scheme introduces the idea of parity gate and uses the non-destructive measurement method based on homodyne detection, which is easier to implement in experiment.

Entanglement generation with coherent light via cross-Kerr-nonlinearity

Zhi‐Ming Zhang, Jian Hua Yang, Ya‐Fei Yu

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 between two modes and the W states among three modes, we find plentiful new kinds of entangled states. Finally, the scheme can be extend to generate the entangled states among more than three modes.

Generation of cluster-type entangled coherent states using weak nonlinearities

Nguyen Ba An, Kisik Kim, Jaewan Kim

We propose a scheme to generate a recently introduced type of entangled coherent states using realistic weak cross-Kerr nonlinearities and intense laser beams. An intense laser can be filtered to make a faint one to be used for production of a single photon which is necessary in our scheme. The optical devices used are conventional ones such as interferometer, mirrors, beam-splitters, phase-shifters and photo-detectors. We also provide a detailed analysis on the effects of possible imperfections and decoherence showing that our scheme is robust against such effects.
