This project will investigate protocols for implementing quantum physically unclonable functions (QPUFs) in secure architectures, both classical and quantum; and theoretically-secure, practical protocols for quantum communication. To implement QPUFs, the student will define a set of figures of merit for assessing the performance of devices against, and then refine algorithms for reading the devices that optimises for these figures of merit. Data will be taken from simulated devices, and structures that have been fabricated in Lancaster's Quantum Technology Centre and analysed with novel techniques developed by the student.This project has strong theoretic and computational elements but will also have practical elements. The student will be trained in experimental skills, learning to take optical and electronic measurements of integrated semiconductor devices. Simulations and calculations will be conducted using Matlab code, developed by the student with guidance from the supervisor. In the assessment of performance of security devices, the student is exploring reformulations of distance metrics and entropy measurements to both judge performance against figures of merit, and to accompany the data as a supplement. The student is implementing Matlab code to test novel measurement techniques developed specifically for the analysis of QPUFs.An investigation of novel communication protocols, as well as existing cryptographic primitives will aim to realise implementations of such protocols in practical and feasible ways experimentally. For the investigation of novel communication protocols, the student shall work alongside experimentalists, laying out the theoretical and mathematical background of novel proposals for protocols such as Quantum Digital Signatures (QDS) and exploring avenues for feasible and practical implementations within laboratories. The student will work as part of an integrated team, meeting informally with PDRAs and the supervisor on a daily basis. Formal, weekly meetings, will monitor progress of the project.

该项目将研究在安全架构中实现量子物理不可克隆功能（QPUF）的协议，包括经典和量子;以及理论上安全，实用的量子通信协议。为了实现QPUF，学生将定义一组用于评估器件性能的品质因数，然后改进用于阅读优化这些品质因数的器件的算法。数据将取自模拟设备，以及在兰开斯特量子技术中心制造的结构，并使用学生开发的新技术进行分析。该项目具有很强的理论和计算元素，但也有实践元素。学生将接受实验技能培训，学习对集成半导体器件进行光学和电子测量。模拟和计算将使用Matlab代码进行，由学生在导师的指导下开发。在安全设备的性能评估中，学生正在探索距离度量和熵测量的重新表述，以根据品质因数来判断性能，并将数据作为补充。学生正在执行Matlab代码来测试专门为QPUFs分析开发的新型测量技术。对新型通信协议以及现有加密原语的研究旨在以实际可行的实验方式实现此类协议的实现。对于新的通信协议的调查，学生将与实验人员一起工作，为协议（如量子数字签名（QDS））的新建议奠定理论和数学背景，并探索实验室内可行和实际实施的途径。学生将作为一个综合团队的一部分工作，每天与PDRA和主管非正式会面。正式的每周会议将监测项目的进展情况。
