Quantum information science with SPAD array technology

这个博士学位是光子学，光学和量子科学的研究项目。这个博士项目的目标是开发，应用和测试单光子敏感探测器（SPAD）阵列技术，用于测量大规模高维光量子态。SPAD阵列是一种新兴技术，已开发用于生物成像和显微镜，但它们在量子科学中的应用有限。然而，它们承诺能够同时测量多个单光子状态，因此是一种可应用于量子成像，量子通信和量子基础的技术。该项目的一个关键目标是建立必要的操作性能参数，如暗计数，效率和时间分辨率，SPAD阵列在量子科学中的使用。这将应用于非局域性，高维纠缠和量子态鉴别的测试。这主要是一个实验性的博士学位，但该项目弥合了量子协议的实验实现和必要的理论要求之间的差距。因此，学生将开发数值模拟来预测应用于量子科学中特定测试和协议的SPAD阵列技术的性能。在建立了必要的参数之后，我们将进行实验来测量高维量子态，并将这些信息提供给下一代量子传感器的设计者和开发者。

This PhD is a research project in photonics, optics, and quantum science. This goal of this PhD project is the development, application, and testing of single-photon sensitive detector (SPAD) array technology for the measurement of large-scale high-dimensional quantum states of light. SPAD arrays are an emerging technology, that have been developed for applications in bioimaging and microscopy, but they have had limited application in quantum science. However, they promise the ability to measure multiple single-photon states simultaneously, and as such, are a technology that can be applied to quantum imaging, quantum communications, and quantum foundations. A key objective of the project is establishing the necessary operational performance parameters, such as dark counts, efficiency, and temporal resolution, of SPAD arrays necessary for use in quantum science. This will be applied in tests of non-locality, high-dimensional entanglement, and quantum state discrimination. This is primarily an experimental PhD, but the project bridges the gap between the experimental realisation of quantum protocols and the necessary theoretical requirements. As such, the student will develop numerical simulations to predict the performance of the SPAD array technologies applied to specific tests and protocols in quantum science. Having established the necessary parameters, we will then perform experiments to measure high-dimensional quantum states and feed this information to the designers and developers of the next generation of quantum sensors.
