The n -Qubit W State of Ground-State Atoms Using Cavity QED and Single Photon Detection

Abstract

We present a simple scheme for the probabilistic generation of the n -qubit W state of three-level systems in cavity quantum electrodynamics. Once the W state is prepared, it will be insensitive to the spontaneous emission of atoms due to the fact that only the two degenerate ground states of the three-level atoms are involved. With time evolution of the system, the success probability and the experimental feasibility are also discussed.

Simple scheme for generating an n -qubit W state in cavity QED

Zhi Jiao Deng, Mang Feng, K. Gao

A simple scheme is proposed to generate an $n$-qubit $W$ state in cavity QED. Conditioned on no photon leakage from the cavity, the $n$-qubit $W$ state can be generated by resonant interaction between atoms and the cavity if the cavity is initially prepared in the single-photon state and all the atoms are in the ground states. We check the time evolution of the system involving decay, and show that, since the required interaction time is very short, with present cavity QED techniques, the success probability of our scheme is almost unity.

Preparation of the W State of Atoms in a Single Cavity or N Distant Cavities by Photon Interference

路洪, 陈立冰, 陈伟成 +1 more

We suggest two schemes to generate the W state of N A-type three-level atoms. In the schemes, identical N three-level atoms are trapped in a cavity or N distant cavities. The success or failure of the generation of the W state can be determined by detecting the polarization of photon leaking out of the cavity. The result demonstrates that the W state is free from both the cavity loss and the spontaneous emission due to the fact that the two ground states (left and right) of the three-level atoms are stable states (or metastable states).

Preparation of Three-atom Entangled W StateVia Resonant Atom-field Interaction

Shao-Hua Xiang

We present a simple and realizable scheme to generate three-atom entangled W state, based on the resonant interaction of three two-level atoms with one single-mode cavity field. It is shown that such state can easily be achieved by controlling the interaction time of atom-cavity-field and the coupling constant without the detection of photon number within the cavity. In addition, the experimental feasibility within the realm of cavity QED is analyzed.

Generation of two-photon EPR and W states

Wesley Bueno Cardoso, Wen-Chao Qiang, Ardiley Torres Avelar +1 more

In this paper we present a scheme for generation of two-photon EPR and W states in the cavity QED context. The scheme requires only one three-level Rydberg atom and two or three cavities. The atom is sent to interact with cavities previously prepared in vacuum states, via two-photon process. An appropriate choice of the interaction times one obtains the mentioned state with maximized fidelities. These specific times and the values of success probability and fidelity are discussed.

Entangled W State Generation via Adiabatic Passage in Cavity QED

Ma Song-She

A scheme is proposed to generate W state of N atoms trapped in a cavity, based on adiabatic passage along dark state. Taking advantage of adiabatic passage, the atoms have no probability of being excited and thus the atomic spontaneous emission is suppressed. The scheme is simple. It does not need to adjust the interaction time accurately, and does not need to prepare the cavity field in one-photon state. Numerical simulation shows that the successful probability of the scheme increases with the increasing of the atom number.
