项目摘要

I will be joining Professor Mehul Malik's group Beyond Binary Quantum Information (BBQ lab) at Heriot-Watt University. I will be working under the joint supervision of Professor Malik and Dr Wollmann. My PhD will focus on the thermodynamic modelling of quantum measurements. This work will be based on a paper titled 'Ideal Projective Measurements Have Infinite Resource Costs' by Y. Guryanova et. al. [1]. It has been shown that there is an infinite thermodynamic resource cost to perform ideal projective measurements, even when the system and pointer are perfectly correlated [2]. This fact hints at the thermodynamic properties of a quantum measurement process. We are interested in investigating models of quantum measurements that agree with this statement as well as with the laws of thermodynamics. Currently, there have been few examples of experimental work implementing quantum thermodynamics in photonics [3] [4]. We aim to fill this gap by designing a scheme that will act as a proof-of-principle demonstration for the resource costs of projective measurements using high-dimensional photonics. Aside from quantum thermodynamics, I will also study entanglement certification methods, particularly in high dimensions. Malik's group are experts in this, with experience with encoding information in the high-dimensional spatial degrees of freedom of a photon.

我将加入赫瑞瓦特大学Mehul Malik教授的小组Beyond Binary Quantum Information （BBQ lab）。我将在Malik教授和Wollmann博士的共同指导下工作。我的博士研究方向是量子测量的热力学建模。这项工作将基于Y. Guryanova等人的一篇题为“理想的投影测量具有无限的资源成本”的论文。它已经表明，有一个无限的热力学资源成本进行理想的投影测量，即使当系统和指针是完全相关的[2]。这一事实暗示了量子测量过程的热力学性质。我们感兴趣的是研究符合这一陈述以及热力学定律的量子测量模型。目前，在光子学中实现量子热力学的实验工作很少。我们的目标是通过设计一种方案来填补这一空白，该方案将作为使用高维光子学进行投影测量的资源成本的原理验证演示。除了量子热力学，我还将研究纠缠证明方法，特别是在高维。Malik的团队是这方面的专家，他们有在光子的高维空间自由度中编码信息的经验。
