用傅里叶变换解决移位问题和隐陪集问题

Solving Shift Problems and Hidden Coset Problem Using the Fourier Transform

Lawrence Ip

摘要:

给出了求解Z/nZ和有限域上的移位乘法特征标问题的量子算法。我们表明,该算法可以被解释为一个矩阵分解或作为解决反卷积问题,并给出充分条件的移位问题,我们的算法有效地解决。我们还表明,结合转移问题与隐藏子群问题的结果在一个隐藏陪集问题。这自然地捕获了由于Z/nZ上的乘法字符的周期性结构而引起的移位中的冗余。

英文摘要:

We give a quantum algorithm for solving a shifted multiplicative character problem over Z/nZ and finite fields. We show that the algorithm can be interpreted as a matrix factorization or as solving a deconvolution problem and give sufficient conditions for a shift problem to be solved efficiently by our algorithm. We also show that combining the shift problem with the hidden subgroup problem results in a hidden coset problem. This naturally captures the redundancy in the shift due to the periodic structure of multiplicative characters over Z/nZ.
