Free-space quantum key distribution(QKD) plays an important role in the global quantum network. However, free space channels suffer from the atmospheric turbulence and scattering effects of haze,fog, and dust, which significantly weaken the performance of QKD or even block the secure quantum ***, we prove the performance of QKD over a dynamic scattering channel can be enhanced significantly using a fast wavefront shaping technique. The system achieves on average 10-dB enhancement of quantum transmission efficiency and establishes a secure quantum link for QKD. Our work demonstrates the feasibility of QKD through free-space dynamic scattering channels and enhances the deployment capability of complex-channel QKD system.

极化指的是波偏振的方式,是波的一个基本性质.利用波的极化可以进行信息的编码,这一编码方式在光学和声学中得到广泛应用.利用自旋波进行信息的传递和处理是磁子学的主要研究课题.然而在铁磁材料中,由于只存在右旋极化的自旋波,利用波的极化进行信息的编码在铁磁自旋波器件中始终没有实现.前期研究发现,通过自旋极化电流可以在铁磁体中产生左旋极化自旋波,从而有望实现利用极化编码的自旋波器件.然而在一个均匀磁化铁磁体中产生左旋极化自旋波所需的电流密度过大,实验上难以实现.磁畴壁可作为自旋波波导,且畴壁中自旋波的截止频率趋近于零.本文从朗道-栗弗席兹方程出发,研究了在自旋极化电流存在的条件下磁畴壁中自旋波的色散关系和传播特性,证明只需要很小的自旋极化电流就可在畴壁中产生稳定的左旋极化自旋波.微磁学模拟证明了理论分析结果.该项研究为研制基于极化编码信息的自旋波器件提供了一个实际可行的方案.

任何现代化探索都会呈现出独特的现代化话语。历史证明,西方发达国家通过中心主义话语叙事建构了现代化的西方话语体系,形成了独占性、绝对性、支配性的西方现代化话语思维,直接影响后发国家的现代化认知与实践。在中国式现代化实现的历史性变革中,现代化话语得以重塑,基于中国实践、具有中国特色、呈现中国风格的社会主义现代化话语显示出了独特的话语特征。全面推进中国式现代化必须加强话语建构,应按照话语生成的“动机—过程—结果”的内在逻辑,在解蔽“政治战略化”“霸权化”“意识形态化”等西方现代化话语的限制性条件的同时,充分考量“历史—现实—未来”等三个基本路向,提出中国式现代化话语建构的原则、思路、指向,丰富现代化话语的多样性并提供新的建构理路。最终,在“历史—道路—文明”的中国式现代化话语叙事中,真正形成关于人类现代化的变革性认识和创新性解释,实现中国式现代化话语的创造性发展。

在数字化时代的浪潮中,国家治理正经历着一场划时代的变革。数字技术的兴起不仅彻底重构了国家治理架构,更孕育了国家治理现代化的全新逻辑体系。面对数字化与国家治理深度融合所带来的治理结构质的飞跃,需要超越表层的复杂性,洞察国家治理深层的运作机制,确立其本质的秩序。在此过程中,首先要明确数字化时代国家治理现代化在本质上何以成为一种原生性创新。因此,需要深入剖析数字化与国家治理之间的建构性关系。从生成论的视角出发,引入“逻辑构序”的概念有助于探究技术与治理之间的相互建构机制、发展过程以及运行和发展的秩序框架。由此,能够在整体上提升对数字化时代国家治理现代化的内在逻辑与结构关系的解释力,有效构建一个清晰的全方位新秩序。深刻理解技术与治理的互构关系,有助于推动国家治理体系与治理能力现代化。通过深入分析数字化背景下的治理实践,能够揭示技术与治理的互构性,阐明“理念—工具—对象”的构序维度在数字治理中的关键作用。为了实现治理的有序性、稳定性和灵活性,数字化时代的国家治理需要在构建治理体系、提升治理能力、解决治理问题等方面实现真正的现代化构序,持续优化技术与治理的交互作用,充分发挥数字治理的优势。
