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.

该项目旨在提供对高维系统中信息和安全的新理解，并利用这一点为量子通信和量子密码技术提供安全，高容量的量子图像传输协议。在量子物理学中，对一个整体的最佳可能的知识并不包括对各个部分的最佳可能的知识：不知道一个单词的任何字母并不意味着不知道这个单词是什么。这个项目旨在研究光子的高维横向空间模式，以证明匡威也是正确的：不知道这个单词并不意味着不知道任何字母。项目成果可用于遥感和监测。
