量子布尔函数

Quantum boolean functions

Ashley Montanaro, Tobias J. Osborne

摘要:

本文介绍了量子布尔函数的研究,它是幺正算子f,其平方是单位元:f^2 = I。我们描述了几个概括的知名结果在理论的布尔函数,包括量子性质测试;量子版本的Goldreich-莱文算法找到大傅立叶系数的布尔函数;和两个量子版本的定理Friedgut,Kalai和Naor的傅立叶谱的布尔函数。为了得到这些推广之一,我们证明了量子推广的超压缩不等式的Bonami,格罗斯和Beckner。

英文摘要:

In this paper we introduce the study of quantum boolean functions, which are unitary operators f whose square is the identity: f^2 = I. We describe several generalisations of well-known results in the theory of boolean functions, including quantum property testing; a quantum version of the Goldreich-Levin algorithm for finding the large Fourier coefficients of boolean functions; and two quantum versions of a theorem of Friedgut, Kalai and Naor on the Fourier spectra of boolean functions. In order to obtain one of these generalisations, we prove a quantum extension of the hypercontractive inequality of Bonami, Gross and Beckner.
