一个精确量子隐子群算法及其在可解群中的应用

An exact quantum hidden subgroup algorithm and applications to solvable groups

Muhammad Imran, Gabor Ivanyos

摘要:

针对$Z_{m^k}^n$中的隐子群问题,给出了一个多项式时间的精确量子算法.该算法使用量子傅里叶变换模m,不需要m的因式分解。对于平滑m,即,当m的素因子的大小为poly(log m)时,量子傅里叶变换可以用Cleve和Coppermith独立发现的方法精确计算,而对于一般的m,可用Mosca和Zalka的算法。即使对于m=3和k=1,我们的结果似乎也是新的。我们还提出了应用程序来计算阿贝尔和可解群的结构,其顺序具有相同的(但可能是未知的)素因子作为M。可解群的应用还依赖于Watrous提出的一种计算子群元素一致叠加的技术的精确版本。

英文摘要:

We present a polynomial time exact quantum algorithm for the hidden subgroup problem in $Z_{m^k}^n$. The algorithm uses the quantum Fourier transform modulo m and does not require factorization of m. For smooth m, i.e., when the prime factors of m are of size poly(log m), the quantum Fourier transform can be exactly computed using the method discovered independently by Cleve and Coppersmith, while for general m, the algorithm of Mosca and Zalka is available. Even for m=3 and k=1 our result appears to be new. We also present applications to compute the structure of abelian and solvable groups whose order has the same (but possibly unknown) prime factors as m. The applications for solvable groups also rely on an exact version of a technique proposed by Watrous for computing the uniform superposition of elements of subgroups.
