Abstract

A kind of entangle coherent states is constructed. According to dual mode field’s sum and difference operators defined by Mark Hillery, its squeezing properties are investigated by means of numerical calculation. Results show that the states appear sum and difference squeezing effect under the given conditions.

Highlights

  • The quantum entangle is a basic characteristics different with non-classical physics in quantum mechanics

  • Squeezing effects of optical field reflects a kind of non-classic properties

  • According to the concepts of sum and difference operator introduced by Mark Hillery about two mode radiation field, by means of using numerical theology, non-classical properties of entangle coherent states are investigated

Summary

Introduction

The quantum entangle is a basic characteristics different with non-classical physics in quantum mechanics. Following the development of quantum information, the entangle states are considered as a kind of important physical resource. Up to now, they have been applied in the region such as quantum computation, teleportation (Bennett C H, Brassard G, Crepeau C, et al 1993), dense coding(Bennett C H, Wiesner S J. Squeezing effects of optical field reflects a kind of non-classic properties. They have extensive application in optical communication, high precision measurement and weak signal detection Sum and difference squeeze effects of entangle coherent states are discussed by using sum and difference operator introduced by Mark Hillery (Hillery M. 1989)
