Introduction在上一学期中,我们讲到了上册中若干量子算法。在这一学期中,我们将主要介绍如何用量子状态表示和传送信息。具体而言,我们将介绍真实世界中量子信息处理时的量子噪声以及运算相关的量子信道;刻画两个量子态表达信息相近程度的度量,探讨量子信道对量子信息的保持;给出经典信息熵的量子版本来研究量子系统中的不确定性;介绍常见的量子纠错码来抵抗量子噪声;介绍由量子信息许多特有性质产生的可证明安全性的量...
PrerequisiteA basic knowledge of quantum mechanics is required.AbstractThis course will provide a general introduction to the theoretical part of tensor networks. The main contents include symmetric tensor network representation, fermionic tensor network representation, tensor network representation of typical topological quantum states, as well as connections between tensor network representat...
