数论、特殊函数与量子信息创新团队的研究领域为数论和函数不等式、非交换Iwasawa代数(代数数论)、量子信息理论。
函数不等式是数学的基础研究领域之一,其结论在数论、几何、分析、方程、物理等领域都有着广泛的应用。非交换Iwasawa代数是新兴的重要基础前沿研究领域之一,来源于数论和算术代数几何,这些有拓扑性质的代数的结构不为人们所熟知,了解其环论性质对数论、算术代数几何等都有非常重要的意义。量子信息是通过量子系统的纠缠、不可克隆等相干特性进行计算、编码和信息传输的全新信息处理方式,具有不可估量的应用前景。团队主要致力于研究一些特殊函数的不等式理论及其在数论中的应用、Iwasawa代数的环论性质及其在椭圆曲线等数学前沿领域中的应用、探索量子纠缠和量子非局域性之间的关系等。
目前该研究团队在此方面“标志性”成果和创新性贡献简述如下:
(1)在理论上提出了对数完全单调函数的概念,此概念已成为数学理论中的一个基本概念和标准术语。此领域的研究在国内外处于领先地位。
(2)在非交换Iwasawa代数的结构的研究成果目前主要集中在正规元方面。这些研究已经初步应用于Iwasawa代数的理想及椭圆曲线算术研究。
(3)在最大纠缠态的量子非局域性的研究取得了一系列成果,这些成果已经在量子密码协议中得到应用。
