Scheme for Preparation of the W State via Cavity QED

Abstract

We put forward a scheme for preparation of an entangled multiparty W state between different modes of radiation field inside high-Q cavity QED. Our scheme is based on the interaction of a two-level atom with the cavity field with the assistance of a strong classical driving field for precalculated interaction time. In principle, the scheme can be extended to prepare an N-party W state. The required experimental techniques are within the scope of what can be obtained in the microwave cavity QED setup.

PREPARATION OF ENTANGLED STATES OF CAVITY FIELD VIA COUPLING TO SUPERCONDUCTING QUANTUM INTERFERENCE DEVICE

Zhiming Zhan

Based on the interaction of a superconducting quantum interference device (SQUID) with the field in high-quality QED and a classical microwave pulse, we propose a scheme for preparing an entangled multipartite W state between different modes of cavity field. In principle, the scheme can be extended to generate a N-party W state. Moreover, the scheme can be used for the generation of multimode entangled coherent states.

Strong-Driving-Assisted Probabilistic State Preparation in Cavity QED

Zhen‐Biao Yang

An alternative scheme is proposed for preparing the superpositions of coherent states with controllable weighting factors along a straight line for a cavity field. The scheme is based on the interaction of a single-mode cavity field with a resonant two-level atom driven by a strong classical field. It is in contrast to the previous methods used in cavity QED of injecting a coherent state into a cavity via a microwave source. In the scheme, the interaction between the cavity mode and atoms is fully resonant, thus the required interaction time is greatly shortened. Moreover, the present scheme requires smaller numbers of operations. In view of decoherence, a reduction of interaction time and numbers of operations for the state preparation is very important for experimental implementation of quantum state engineering.

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.

We present a scheme for the generation of entanglement between different modes of radiation field inside high-$Q$ superconducting cavities. Our scheme is based on the interaction of a three-level atom with the cavity field for precalculated interaction times with each mode. This work enables us to generate a complete set of Bell basis states and a quantum entangled Greenberger-Horn-Zeilinger state.
