中文摘要：

在这篇论文，遥远的准备的理论调查关于， angled 状态处于非理想的条件被学习。我们的研究包括二部分。在第一部分，我们认为也就是，通过二条同等地吵闹的量隧道的一个纠缠的状态的遥远的州的准备(RSP ) 说贝尔状态的混合物。研究证明有所有纯纠缠的状态为仍然保持在这不精确的 RSP 以后纠缠了的一条 particularmixed 状态隧道。Inthe 秒部分，我们假定隧道受不了量的噪音能被表示为 theLindblad 操作员。系统的主人方程能在 Lindblad 形式被表示。Throughsolving 主人方程，我们作为 decoherence 率的功能和要准备的状态的参数计算忠实。为一个给定的纠缠的状态，我们在忠实上调查噪音的不同类型的影响。

英文摘要：

In this paper, the theoretical investigation of remote preparation of an entangledstate is studied in nonideal conditions. Our studies include two parts. In the first part, we consider the remote state preparation （RSP） of an entangled state through two equally noisy quantum channel states, namely, a mixture of Bell states. Studies show there is a particular mixed-state channel for which all pure entangled states remain entangled after this inexact RSP. In the second part, we suppose that noises which quantum channels suffer from can be expressed as the Lindblad operators. The master equation of the system can be expressed in the Lindblad form. Through solving the master equation, we calculate the fidelity as a function of decoherence rates and parameters of the state to be prepared. For a given entangled state, we investigate the influence of different types of noises on the fidelity.
