ON THE INTERMEDIATE STATES OF THE LIGHT FIELD

Clodoaldo Valverde, B. Baseia

Published Dec 1, 2004• 10 citations
Publisher

Abstract

This paper is a short survey on intermediate states (IS) of the light field studied in the last fifteen years in the literature; they coincide with two basic states in two different limits of the involved parameters. We consider their main characteristics, distinguishing them in two classes: the class of interpolating states, and a special class of superposition states. A new IS is proposed to compare properties of distinct states mapping between the same extremes.

On a new intermediate state of the quantized radiation field

Andreísa Fabri Lima, B. Baseia, Gil C. Marques

In a recent paper we introduced the intermediate number-phase state (INPS) of the quantized radiation field, which interpolates between the number state |n> and the phase state |θ >. Various non-classical properties of the light field in this state (sub-Poissonian statistics, antibunching and squeezing effects) were investigated. Here, looking for a criterion characterizing the INPS as a “good” interpolating state, we investigate the influence of the interpolating parameters upon the variances and uncertainty relation involving the number and phase operators in this state.

Quantum Superpositions of Binomial States of Light

A. Vidiella-Barranco, José Antonio Roversi

We introduce new kinds of states of electromagnetic field, which are quantum superpositions of binomial states. They not only exhibit remarkable non-classical properties but can also interpolate between the ‘Schrödinger cat’ type of states and the number states in a particularly interesting way. We basically discuss some of their main statistical properties, as well as schemes for their generation. We also employ quasiprobability distributions in phase space.

GENERATION OF NONCLASSICAL STATES OF LIGHT FIELD BY ORTHO-SYMMETRIZATION

彭石安

In recent years, nonclassical effects of light field havealways been a very conspicuous subject. In this field an effective approach is to construct as many as possible the nonclassical states of light field that are allowed in the frame of quantum mechanics and then to study their properties, so as to find out the relations of different nonclassical effects or states of light field and to discover new nonclassical effects or states of light field.

Superposition of displaced number states and interference effects

CELIA M. A. DANTAS, José Rildo de Oliveira Queiroz, B. Baseia

We introduce a new state of light field by superposing two displaced number states having a phase difference between them in the phase space. The influence of this phase upon its various non-classical properties is investigated, including a discussion on the generation of this state, which contains as particular cases important states studied in the literature.

Properties of hybrid entanglement between discrete- and continuous-variable states of light

L S Costanzo, Alessandro Zavatta, Samuele Grandi +5 more

We discuss some of the main features of a recently-generated form of hybrid entanglement between discrete- and continuous-variable states of light. Ideally, such a kind of entanglement should involve single-photon and coherent states as key representatives of the respective categories of states. Here we investigate the characteristics and limits of a scheme that, relying on a superposition of photon-creation operators onto two distinct modes, realizes the above ideal form of hybrid entanglement in an approximate way.

Intermediate coherent-phase(PB) states of radiation fields and their nonclassical properties

Zhang, Y, Fu, H, A. I. Solomon

Intermediate states interpolating coherent states and Pegg-Barnett phase states are investigated using the ladder operator approach. These states reduce to coherent and Pegg-Barnett phase states in two different limits. Statistical and squeezing properties are studied in detail.
