The Non-Classical Properties of Squeezed Orthogonal Coherent States

Yongping Li

Published Jan 1, 2005• 0 citations

Abstract

The non-classical properties of orthogonal coherent state in parametric amplification process are investigated. After this nonlinear optical interaction, orthogonal coherent states exhibit both squeezing and anti-bunching, which is very different from the squeezed coherent states and squeezed even and odd coherent states.

New even and odd nonlinear coherent states and their non-classical properties

Meng Xiang-Guo, Ji‐Suo Wang, 聊城大学物理系,聊城 252059

A new kind of even and odd nonlinear coherent states (EONLCS) is constructed. Using the numerical computation method, the non-classical properties such as squeezing, amplitude-squared squeezing, anti-bunching and phase probability distribution of the new EONLCS are investigated. The results show that, in the different ranges of the parameter |λ|, the new EONLCS exhibits amplitude-squared squeezing in the directions Y1 and Y2. The squeezing effect is shown in the direction X2 for new even nonlinear coherent states, and the anti-bunching effect is shown for new odd nonlinear coherent states. Moreover, we find that the new EONLCS exhibit different quntum interference properties by studying the probability distributions of the states.

Non-classical Properties of Even and Odd Coherent States

Christopher C. Gerry

We present a detailed discussion of even and odd coherent states defined as eigenstates of the single mode two-photon annihilation operator a 2. We study the non-classical properties such as squeezing, higher-order squeezing, and photon antibunching. Also discussed are the various quantum quasiprobability distributions, namely the P function, which is shown to be highly singular, the Q function, and the Wigner, which can take on negative values for these states. Finally, we present a discussion of a possible mechanism for the generation of such states based on the competition between parametric amplification and the incoherent losses from two-photon resonant absorption.

A new kind of even and odd nonlinear coherent states and their quantum statistical properties

Jian‐Sheng Wang, Jie Feng, TK Liu +1 more

A new kind of even and odd nonlinear coherent states are defined. Using the numerical method, we have studied quantum statistical properties of the new even and odd nonlinear coherent states. It is shown that quantum statistical properties of the new even and odd nonlinear coherent states are very different from those of the usual even and odd coherent states. It is found that, in some ranges of 1beta1, the squeezing only exists in the new even nonlinear coherent state, and the amplitude-squared squeezing and antibunching effect appear for both new even and odd nonlinear coherent states.

Nonclassical statistical properties of fields in squeezed even and squeezed odd coherent states

Kaicheng Zhu, Xiangru Li, Qin Wang

We examine the nonclassical statistical properties of the squeezed even and the squeezed odd coherent states defined by the superposed states involving two squeezed coherent states with phase difference π between their displacement parameters. We demonstrate that the fields in the squeezed even coherent state can exhibit a remarkably enhanced squeezing level and mean photon number in comparison with the input squeezed coherent state. We also give examples of physical processes that lead to such a superposition.

Non classical Properties of Leading terms Odd and Even Coherent States

Pla Jinan

Squeezing and antibunching effects of Leading terms odd and even coherent states are discussed. The conditions of squeezing and antibunching effect are found, and these photon statistical characteristics are very different from those of the ordinary odd and even coherent states.

Entanglement of Two-Mode Squeezed Even and Odd Coherent States

Wei Wu, Zhong-Ju Liu, Jing Zhang

The two-mode squeezed even and odd coherent states are quantum states with some non-classical properties. The entanglement of two-mode squeezed even and odd coherent states are measured by non-classicality of P-function and separability inequalities of EPR-operators.
