代数性质的量子查询复杂性

The Quantum Query Complexity of Algebraic Properties

Sebastian Doern, Thomas Thierauf

摘要:

我们提出了量子查询的复杂性界限测试代数属性。对于集合S和S上的二元运算,我们考虑了$S$是半群还是有单位元的判定问题.如果S是幺半群,我们要判断S是否是群。我们提出了量子算法,这些问题,提高了最知名的经典复杂性的界限。特别是,我们给出了新的量子随机游走技术的第一个应用,由Magniez,Nayak,Roland和Santha,提高了以前的界限Ambainis和Szegedy。我们还提出了几个下界测试代数性质。

英文摘要:

We present quantum query complexity bounds for testing algebraic properties. For a set S and a binary operation on S, we consider the decision problem whether $S$ is a semigroup or has an identity element. If S is a monoid, we want to decide whether S is a group. We present quantum algorithms for these problems that improve the best known classical complexity bounds. In particular, we give the first application of the new quantum random walk technique by Magniez, Nayak, Roland, and Santha that improves the previous bounds by Ambainis and Szegedy. We also present several lower bounds for testing algebraic properties.
