摘要

分析辐射到量子频率转换器的高功率光波的环境响应是本文的目的。我们使用非线性光学系统的全量子描述来研究从该系统发射的电磁波的非经典性质。借助旋转波近似和求解信号（强）和闲散（弱）频率的海森堡运动方程，我们研究了产生的输出波的非经典性质，包括压缩、纠缠和量子化场反聚束。解析和数值结果表明，作为量子频率转换器入口波的合数相干态和对相干态可以明显地揭示出这些非经典符号。

The effect of quantum frequency conversion on the quantumness of radiation field states

Analyzing the environmental response to high-power optical waves radiated into a quantum frequency converter is our aim of the paper. We examine the non-classical properties of the electromagnetic waves emitted from this system, using a fully quantum description for this nonlinear optical system. With the help of rotating wave approximation and solving the Heisenberg equations of motion for signal (strong) and idler (weak) frequencies, we study the non-classical properties of the produced output waves, including squeezing, entanglement and quantized field antibunching. Analytical and numerical results evidently confirm that most of these non-classicality signs can be revealed for the composite number and pair coherent states, as the entrance waves to the quantum frequency converter, distinctly.
