Using Quantum Dots to Generate Spin Photon Entanglement

纠缠是量子技术许多应用的重要资源。能够可靠地产生这种资源的一个途径是通过量子点。在这个博士项目中，我将从理论上和实验上探索这种可能性。重点介绍了一种通过带电量子点相干散射产生自旋光子纠缠的新方法。我将开始充实我们提出的协议，理想地显示它产生自旋光子团簇状态。然后，将扩展该协议，以考虑不完美系统的影响。这将包括诸如源失谐，外部磁场和减相等事情。一旦这个理论建立起来，我们就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个理论。最初的目标是利用弱相干光源做一个原理证明实验，最终目标是证明单光子的纠缠。从事这些活动将发展我在光学实验室技术，量子点低温光谱，实验室视图和量子光与物质相互作用理论等重要领域的技能。

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.
