Scheme for preparation of the W-state by using linear optical elements

Abstract

We present an experimental scheme of preparing the three-photon W-state in this paper. This scheme is based on a linear optical element, four polarization-entangled photons produced in spontaneous parametric down-conversion and single-photon detection. Effects of the imperfection of optical elements on nonlocality are also discussed.

Polarization-entangledWstate using parametric down-conversion

Takashi Yamamoto, Kiyoshi Tamaki, Masato Koashi +1 more

An experimental scheme for preparing a polarization entangled W states from four photons emitted by parametric down-conversion is proposed. We consider two different configurations and a method of improving the yield by using single-photon sources. In the proposed scheme, one uses only linear optical elements and photon detectors, so that this scheme is feasible by current technologies.

Generation of an entangled four-photonWstate

Xu‐Bo Zou, K. Pahlke, Wolfgang M. Mathis

We present a scheme to produce an entangled four-photon W state by using linear optical elements. The symmetrical setup of linear optical elements consists of four beam splitters, four polarization beam splitters, and four mirrors. A photon Einstein-Podolsky-Rosen pair and two single photons are required as the input modes. The projection on the W state can be made by a four-photon coincidence measurement. Further, we show that by means of a horizontally oriented polarizer in front of one detector, the W state of three photons can be generated.

Generating a four-photon polarization-entangled cluster state

Xu‐Bo Zou, Wolfgang M. Mathis

We propose a scheme to generate a four-photon polarization-entangled cluster state by using only linear optical elements and four-photon coincidence detection. The scheme requires two single-photon states and one two-photon polarization entangled state as input resources. Then, we consider the realistic implementation of the scheme by using the spontaneous parametric down-conversion as photon resources. It is shown that under certain conditions, the four-photon polarization cluster state can be generated with a high fidelity, and the scheme is feasible by current experimental technology.

Conditional preparation of maximal polarization entanglement

Cezary Śliwa, Konrad Banaszek

A simple experimental setup consisting of a spontaneous parametric down-conversion source and passive linear optics is proposed for conditional preparation of a maximally entangled polarization state of two photons. Successful preparation is unambiguously heralded by coincident detection of four auxiliary photons. The proposed scheme utilizes the down-conversion term corresponding to the generation of three pairs of photons. We analyze imperfect detection of the auxiliary photons and demonstrate that its deleterious effect on the fidelity of the prepared state can be suppressed at the cost of decreasing the efficiency of the scheme.
