disentanglement

Disentanglement refers to the transformation of entangled quantum system intodisentangled system via some physical processes .

所谓消纠缠，是指通过一定的物理过程，使原来纠缠的量子系统变得“不纠缠”。

The main results of this thesis are as follows . 1 . We studied the conditions of atomic finite-time disentanglement in cavity QED .

本文主要内容包括以下几个方面：1.研究了腔量子电动力学（QED）背景中原子有限时间解纠缠发生的条件。

When one 's life quality and living environment go far from his spiritual and material goal that he always pursues , the most real thought is to seek and acquire disentanglement .

当一个人的生活质量，环境和自身追崇的精神和物质理念先去甚远的时候，最真实的想法就是希望得到解脱。

By manipulating the atom outside the field , we can say that entropy evolution of the atom inside the field interacting with light field appears entanglement and disentanglement .

通过操纵腔外的一个原子，原子与光场的演化可以出现纠缠和解纠缠等情况。

Disentanglement agent compounded by ourselves is used , the content of UHMWPE > PP and disentanglement agent influencing on mechanical properties , rheological properties and thermal properties are researched .

在体系中加入自行配制地解缠剂Jc-3，研究了UHMWPE、PP和解缠剂的含量对体系力学性能、流动性能和热学性能的影响。

The results indicate that the atoms ' state is a pure state which is different from its initial state , and the disentanglement between atoms and field arises provided that the atoms are trapped coherently .

结果表明：相干捕获后的原子态为一不同于初态的纯态，原子系统与光场的纠缠分解。

Thus in this thesis , we will made a detailed introduction of our method & perturbation based on unitary transformation , and apply it to several models to investigate the Non-Markovian decoherence and disentanglement dynamics of dissipation two-state system .

本文中，我们介绍一种新的解析方法-基于幺正变换下的微扰理论，并且把此理论应用到具体的实验模型中，推导了耗散二能级系统非马尔可夫退相干和退纠缠动力学。

And detuning , Kerr effect , et al . play an important role for the properties of the quantum entanglement between the atom and the field ( such as evolution period , the degree of entanglement , disentanglement et al . ) .

另外，失谐量、克尔效应、光场的强度等因素对光场与原子之间的量子纠缠动力学的性质（诸如演化周期、纠缠强度、退纠缠等）有重要的影响。

The finite-time disentanglement , which is also termed as entanglement sudden death ( ESD ), refer to the entanglement of a composite system can decay to zero in a finite time , exhibiting clear difference to the exponential decay of the coherence of a single quantum system .

有限时间解纠缠也被称为纠缠猝死（Entanglementsuddendeath），是指复合体系的纠缠可以在有限时间内退化为零，明显不同于单量子系统相干性随时间的指数型衰减。
