摘要
2022 年中国学者提出的量经融合大数分解算法，在近期量子硬件即可尝试破译RSA，引起广泛关注，产生重大影响。量子通信是 “盾”，为信息安全提供新的保护方法。在量子密钥分发快速发展的同时，量子安全直接通信（QSDC）技术也取得快速发展，建立了高噪声下安全通信理论，实现了光纤和空间实验演示，完成了城域、城际和网络三个里程碑系统，并在银行和 5G 专网试用。本报告将介绍近期的进展。
演讲者介绍
Gui-Lu Long is a professor in Tsinghua University & Deputy-President of Beijing Academy of Quantum Information Sciences. He is fellow of IoP and APS. Notably among his contributions, he proposed the quantum secure direct communication that transmits information directly; constructed the Grover-Long algorithm for exact search and the full quantum eigensolver; and established the widely used linear combination unitaries method for quantum algorithm designs. He proposed the WISE interpretation of quantum mechanics. He published 300+ papers with 20000+ citations. He was President of AAPPS and vice-chair of C13 of IUPAP.
