A microfabricated Ion Trap with an Integrated, Monolithic Optical Cavity

该项目将涉及几个步骤，简要概述如下：首先，在建立用于离子-光子和离子-离子纠缠的协议方面将有相当大的理论努力。物理学本身是很好理解的，但这种物理学应用于我们的系统需要仔细规划，以便选择最适合我们需求的协议（如使用哪种电子跃迁的决定），并优化腔参数以实现快速和高保真的纠缠。除此之外，还将对离子阱设计和腔镜进行原型实验。陷阱实验将以类似于最终陷阱的形式产生简单的离子陷阱，以测试这种结构的制造有多现实，以及我们可以从最终陷阱中期待什么特性。反射镜测试将查看反射镜的特性，如散射损耗和双折射。我们计划使用的反射镜并不是按照我们要求的尺寸常规制造的，因此它们在上述方面的性能并不可靠。这些测试的结果将表明哪些/是否任何考虑的协议是可行的，如果性能可以预期从最终系统是值得追求的，除了这将是模拟工作，以预测最终设计的属性。特别值得关注的是电性能（空腔对捕获电势的影响有多强）和机械性能（空腔是否会影响捕获电势）。

The project will involve several steps which are briefly outlined below:Firstly, there will be considerable theoretical effort in establishing the protocol that will be used for the ion-photon and ion-ion entanglement. The physics itself is well-understood, but the application of this physics to our system requires careful planning so that the best protocol (decisions like which electronic transitions to use) for our needs can be chosen and so that the cavity parameters can be optimised for fast and high-fidelity entanglement.Alongside this will run prototyping experiments on ion trap designs and cavity mirrors. The trap experiments will produce simple ion traps in a form similar to the final trap to test out how realistic the fabrication of such structures is and what properties we could expect from the final trap. The mirror tests will look at properties of the mirrors such as scattering loss and birefringence. The mirrors we plan to use are not routinely fabricated in the size we require, so their performance in the aforementioned respects is not reliably known. The results of these tests will indicate which of/whether any of the protocols considered are viable and if the performance one could expect from the final system is worthwhile pursuingIn addition to this will be simulation work to predict the properties of the final design. Specifically of concern are the electrical properties (how strongly the cavity will affect the trapping potential) and the mechanical properties (whethe
