项目摘要

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

该项目将涉及以下几个步骤：首先，将有相当大的理论努力建立协议，将用于离子-光子和离子-离子纠缠。物理本身是很容易理解的，但是将这种物理应用到我们的系统中需要仔细规划，以便为我们的需要选择最佳协议（决定使用哪种电子跃迁），以便优化腔参数以实现快速和高保真的纠缠。除此之外，还将进行离子阱设计和腔镜的原型实验。陷阱实验将产生类似于最终陷阱形式的简单离子陷阱，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望得到什么特性。反射镜测试将考察反射镜的特性，如散射损耗和双折射。我们计划使用的镜子不是按照我们需要的尺寸常规制造的，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所考虑的协议中的哪一个/是否可行，以及人们对最终系统的预期性能是否值得追求。此外，还将进行模拟工作，以预测最终设计的性能。特别值得关注的是电学性能（腔体对捕获电位的影响有多大）和机械性能(是否有
