Knowledge, Ignorance, and Security in Higher-dimensional Quantum Systems

该项目旨在为高维系统中的信息和安全提供新的理解，并利用这一点为量子通信和量子密码技术提供安全、大容量、量子图像传输协议。在量子物理学中，对整体的最好可能知识并不包括对部分的最好可能知识：不知道一个单词的任何一个字母并不意味着不知道这个单词是什么。这个项目的目的是研究光子的高维横向空间模式，以表明反之亦然：不知道这个词并不意味着不知道任何字母。项目成果可能在遥感和监测方面有应用。

This project aims to provide new understanding of information and security in higher-dimensional systems, and to exploit this to deliver a secure, high-capacity, quantum image transfer protocol for quantum communication and quantum cryptography technologies. In quantum physics, the best possible knowledge of a whole does not include the best possible knowledge of the parts: not knowing any of the letters of a word does not imply not knowing what the word is. This project aims to examine the high-dimensional transverse spatial modes of photon to show that the converse is also true: not knowing the word does not imply not knowing any of the letters. Project outcomes may have applications in remote sensing and surveillance.
