一维量子游走的一个解析解

An analytic solution for one-dimensional quantum walks

Ian Fuss, Lang White, Peter Sherman, Sanjeev Naguleswaran

摘要:

首先推导出位置和动量空间中一维游动的一般解析解。这些解决方案揭示了,除其他事项外,新的对称性特征的量子行走概率密度和进一步了解他们的时刻的行为。量子游走概率分布的解析表达式提供了一种模拟量子现象的方法,这种方法类似于经典域中的随机游走。

英文摘要:

The first general analytic solutions for the one-dimensional walk in position and momentum space are derived. These solutions reveal, among other things, new symmetry features of quantum walk probability densities and further insight into the behaviour of their moments. The analytic expressions for the quantum walk probability distributions provide a means of modelling quantum phenomena that is analogous to that provided by random walks in the classical domain.
