某些隐位移问题的量子算法

Quantum Algorithms for some Hidden Shift Problems

Wim van Dam, Sean Hallgren, Lawrence Ip

摘要:

迄今为止,几乎所有最成功的量子算法都利用傅里叶变换来恢复函数的子群结构,特别是周期性。傅里叶变换也可以用来捕捉移位结构的事实在量子计算的背景下受到的关注要少得多。在本文中,我们提出了三个例子的“未知移位”的问题,可以有效地解决量子计算机使用量子傅立叶变换。我们还定义了隐陪集问题,它推广了隐移位问题和隐子群问题。这个框架提供了一种统一的方式来观察傅立叶变换捕获子群和移位结构的能力。

英文摘要:

Almost all of the most successful quantum algorithms discovered to date exploit the ability of the Fourier transform to recover subgroup structure of functions, especially periodicity. The fact that Fourier transforms can also be used to capture shift structure has received far less attention in the context of quantum computation. In this paper, we present three examples of ``unknown shift'' problems that can be solved efficiently on a quantum computer using the quantum Fourier transform. We also define the hidden coset problem, which generalizes the hidden shift problem and the hidden subgroup problem. This framework provides a unified way of viewing the ability of the Fourier transform to capture subgroup and shift structure.
