Entanglement is an important resource for many applications of Quantum technology. One path to being able to generate this resource reliably is through Quantum Dots. In this PhD project I will be exploring this possibility both theoretically and experimentally. Focusing particularly on a new protocol to generate spin-photon entanglement via coherent scattering with a charged Quantum Dot.I will begin by fleshing out our proposed protocol, ideally showing that it generates spin-photon cluster states. This protocol will then be extended to consider effects from an imperfect system. This will include things such as source detuning, external magnetic fields, and dephasing.Once this theory has been established and we can make predictions about the systems behaviour then we will begin implementing this theory in practice. The initial goal will be to do a proof of principle experiment utilizing a weak coherent light source with the end goal of moving to demonstrating entanglement with single photons.Undertaking these activities will develop my skills in important areas such as optical laboratory techniques, low temperature Spectroscopy of Quantum Dots, lab view and Quantum light and matter interaction theory.

纠缠是量子技术许多应用的重要资源。能够可靠地生成这种资源的一种方法是通过量子点。在这个博士项目中，我将从理论和实验两方面探索这种可能性。特别关注一种通过与带电量子点的相干散射产生自旋光子纠缠的新协议。我将从充实我们提出的协议开始，理想地展示它产生自旋光子簇态。然后，该协议将被扩展，以考虑来自不完美系统的影响。这将包括源失谐、外加磁场和退相等内容。一旦这一理论建立起来，我们可以对系统的行为做出预测，然后我们将开始在实践中实施这一理论。最初的目标是利用弱相干光源进行原理验证实验，最终目标是演示单光子纠缠。通过这些活动，我将在光学实验室技术、量子点低温光谱、实验室观点和量子光与物质相互作用理论等重要领域发展我的技能。
