量子态的几何复杂性

Algorithmic complexity of quantum states

C. Mora, H. J. Briegel

摘要:

本文定义了纯量子态的Kolmogorov复杂度。在经典信息论中,字符串的算法复杂度是通用机器复制字符串本身所需信息的度量。我们定义的复杂性的量子态的经典描述的复杂性的(抽象)的实验程序,使我们能够准备一个给定的保真度的状态。我们认为,我们的定义满足了复杂性作为衡量准备状态“有多难”的直观想法。我们应用这个定义给一个上限的算法复杂性的一些国家。

英文摘要:

In this paper we give a definition for the Kolmogorov complexity of a pure quantum state. In classical information theory the algorithmic complexity of a string is a measure of the information needed by a universal machine to reproduce the string itself. We define the complexity of a quantum state by means of the classical description complexity of an (abstract) experimental procedure that allows us to prepare the state with a given fidelity. We argue that our definition satisfies the intuitive idea of complexity as a measure of ``how difficult'' it is to prepare a state. We apply this definition to give an upper bound on the algorithmic complexity of a number of states.
