Quantum walks are a kind of basic quantum computation model. Quantum walks with memory(QWM) are types of modified quantum walks that record the walker’s latest path. In this paper we present QWM-P, a kind of QWM whose evolution depends on the parity of memory. QWM-P has an identity coin shift function which helps in analyzing and designing algorithms. Then we discuss some properties of QWM-P. We find that the parity of memory length affects the appearance of QWM-P.

内存奇偶校验提供内存的量子行走

量子行走是一种基本的量子计算模型。带记忆的量子行走(QWM)是一种修改后的量子行走,它记录了行走者的最新路径。在本文中,我们介绍了 QWM-P,这是一种 QWM,其演化取决于内存的奇偶校验。QWM-P 具有身份硬币转移功能,有助于分析和设计算法。然后我们讨论 QWM-P 的一些性质。我们发现内存长度的奇偶校验会影响 QWM-P 的外观。
