Maximally entangled states of a bimodal cavity field

Published Oct 1, 2000• 3 citations

Abstract

A simple scheme for the generation of a class of maximally entangled two-mode field states is presented. Our proposal provides the possibility of manipulating the quantum coherence between the superposed states, simply varying an experimentally easily controllable parameter. The practical feasibility of the method here reported is carefully discussed.

Generation of maximally entangled states of two cavity modes

Farhan Saif, Mahmoud Abdel‐Aty, M. A. Javed +2 more

In this letter we present a scheme for generating maximally entangled states of two cavity modes which enables us to generate complete set of Bell basis states having rather simple initial state preparation. Furthermore, we study the interaction of a two-level atom with two modes of electromagnetic field in a high Q cavity. The two-level atom acts as a control qubit and the two mode electromagnetic field serves as a target qubit. This simple system of quantum electrodynamics provides us experimentally feasible universal quantum logic gates.

Scheme for Generation of Entanglement among Bimodal Cavities

Song Xin-Guo, Feng Xun-Li

We present a scheme for generation of an entangled state in many spatially separated bimodal cavity modes via cavity quantum electrodynamics. A V-type three-level atom, initially prepared in a coherent superposition of its excited states, successively passes through both the bimodal cavities. If the atom is measured in its ground state after leaving the last cavity, an entangled state of many cavity modes can be generated. The conditions to generate the maximally entangled state with unity probability are worked out.

Local entanglement in a bimodal high- Q cavity: Production and utilization

Anna Napoli, Antonio Messina

A new conditional scheme for entangling the two quantized modes of a bimodal high-Q cavity field is presented. We show that, injecting one at time k atoms inside the cavity, it is possible to guide the field toward k-dependent linear combinations of k + 1 bimodal Fock states, each one possessing the same total number of photons. The two simple cases corresponding to the passage of one or two atoms only through the resonator are considered. Their practical feasibility against cavity losses, spontaneous emission and other sources of imprecision of the experimental set-up is discussed. Two examples illustrating the usefulness of and the interest toward the creation of such a local entanglement, are reported. The first one relates the specific features of these bimodal entangled states to the occurrence of a non-classical correlation effect in the dynamics of a two-level atom interacting with the entangled cavity. The second one demonstrates that the peculiar entanglement initially stored in the cavity in accordance with our method, provides an effectively exploitable resource to entangle two spatially separated cavities.

Nonclassical properties and generation of quantum superpositions of two coherent states

Anna Napoli, ANTONINO MESSINA

Nonclassical properties of a particular class of quantum superpositions of two coherent states of a single-mode quantized electromagnetic field are brought to light and discussed. A new and simple way of engineering such states is presented. Our proposal, developed in the context of micromaser theory, exploits the passage of one atom only through a high- Q bimodal cavity supporting two electromagnetic modes of different frequencies.

Generation of maximally entangled states via dispersive interactions

Alfredo Luis

We propose a simple method to generate in practice the most general two-mode states with maximum entanglement. The method is based on energy-conserving dispersive interactions that can be easily implemented in different context such as quantum optical fields, quantum motion of trapped ions, or in Bose-Einstein condensates.

A Cavity-QED Scheme for Generating Long-Lived Maximally Entangled States

Shao-Hua Xiang, Shao Bin, Kehui Song +1 more

We propose a potentially practical scheme to generate two-atom maximally entangled states by the large-detuning interaction between two three-level Λ-type atoms and coherent optical fields. Conditioned on the results of detecting cavity field, four pairs of atomic maximally entangled states with unity fidelity and high successful probability can be prepared. We also investigate the influence of the cavity dissipation on the generated entangled states and discuss the experimental feasibility of our scheme.
