论文摘要
作为量子通信研究最突出的子场之一，远程状态制备（RSP）在量子网络中起着至关重要的作用。在这里，我们提出了一种确定性的远程准备方案，以通过Borras \ emph {et al。}状态创建的七个Qubit的纠缠通道来制备任意的两分Qubit状态。量子噪声是当前正在使用的量子通信的每个协议所固有的，将量子通信系统的完整性及其可靠性置于风险上。系统的初始状态是纯量子状态，但是一旦将系统注入任何噪声，它就会转变为混合状态。在本文中，我们讨论了六种不同类型的噪声模型，即位叉噪声，相叉噪声，比特叶片噪声，振幅阻尼，相阻尼和去极化噪声。通过分析由于噪声而改变的密度矩阵，可以看到这些噪音对纠缠通道的影响。为了分析噪声对该方案的影响，已经评估并以图形方式评估了原始量子状态与远程制备状态之间的保真度。此外，还进行了全面的安全分析，表明建议的协议是安全的，以防止内部和外部攻击。
As one of the most prominent subfields of quantum communication research, remote state preparation (RSP) plays a crucial role in quantum networks. Here we present a deterministic remote state preparation scheme to prepare an arbitrary two-qubit state via a seven-qubit entangled channel created from Borras \emph{et al.} state. Quantum noises are inherent to each and every protocol for quantum communication that is currently in use, putting the integrity of quantum communication systems and their dependability at risk. The initial state of the system was a pure quantum state, but as soon as there was any noise injected into the system, it transitioned into a mixed state. In this article, we discuss the six different types of noise models namely bit-flip noise, phase-flip noise, bit-phase-flip noise, amplitude damping, phase damping and depolarizing noise. The impact these noises had on the entangled channel may be seen by analysing the density matrices that have been altered as a result of the noise. For the purpose of analysing the impact of noise on the scheme, the fidelity between the original quantum state and the remotely prepared state has been assessed and graphically represented. In addition, a comprehensive security analysis is performed, demonstrating that the suggested protocol is safe against internal and external attacks.
