"This is a PhD research project in Physics. The aim of the project is to build a new experimental setup and demonstrate a telecom quantum memory based on rare earth doped crystals. The work program is divided into three phases.Phase-1 is related to building the experimental setup. This will be mainly composed by the cryogenic system and the laser system and will underpin experiments for several years. Phase-2 is related to the coherent spectroscopy of stoichiometric samples and testing of storage protocols in bulk crystals. To mitigate the risks originating from the material choice, different crystals grown by different companies/research groups will be studied.Phase-3 focuses on waveguide integrated memory protocols. Our final objective is to realise fibre-compatible photonic QM on chip, featuring unprecedented functionalities and readily integrable with photon sources and detectors, for quantum networks applications. Indeed, during the final phase of the project, we will benchmark the QM performance by connecting it with quantum dot single photon sources and single photon detectors. "

“这是一个物理学博士研究项目。该项目的目的是建立一个新的实验装置，并展示基于稀土掺杂晶体的电信量子存储器。工作计划分为三个阶段，第一阶段是建立实验装置。这将主要由低温系统和激光系统组成，并将支持几年的实验。阶段2涉及化学计量样品的相干光谱和散装晶体中存储协议的测试。为了减轻材料选择带来的风险，将研究不同公司/研究小组生长的不同晶体。第三阶段侧重于波导集成存储器协议。我们的最终目标是在芯片上实现光纤兼容的光子QM，具有前所未有的功能，易于与光子源和探测器集成，用于量子网络应用。事实上，在该项目的最后阶段，我们将通过将其与量子点单光子源和单光子探测器连接来对QM性能进行基准测试。"
