Quantum photonics is an emergent field of technology promising to revolutionise science and day-to-day life alike. Amongst other benefits, it is anticipated that it will usher in ultra-secure communication, powerful super-fast computers and vastly increased data storage. These advancements are all based on the premise of developing single-photon sources: special sources of light characterised by emitting one photon at a time. Semiconductor quantum dots (QDs), consisting of nanometre-sized inclusions of one semiconductor within another, are atom-like systems emerging as attractive candidates for single-photon sources. However, they operate at very low temperatures requiring liquid helium cooling, which is a major drawback. This significant problem can be overcome by developing nitride QDs capable of emitting single photons at much higher temperatures. This project aims to test the application of Quantopticon's powerful simulation software in a context similar to that in which it might be sold, make it work faster and more effectively and provide it with a user-friendly interface. We will demonstrate that the software can have impact in a technologically important area. Our simulation tools will remove the need to carry out multiple, costly experiments, thus greatly accelerating and optimising the design and manufacture of nitride QD devices.

量子光子学是一个新兴的技术领域，有望彻底改变科学和日常生活。除其他好处外，还可以预期它将引入超安全通信，强大的超快速计算机并大大增加数据存储。这些进步都是基于开发单光子来源的前提：特殊的光源，其特征是一次发出一个光子。半导体量子点（QD），由一个半导体的纳米大小夹杂物组成，是另一个半导体的纳米样系统，是原子状的系统作为单光子来源的有吸引力的候选物。但是，它们在非常低的温度下运行，需要液态氦冷却，这是一个主要缺点。可以通过开发能够在更高温度下排放单个光子的氮化物QD来克服这个重大问题。该项目旨在在类似于可能出售的上下文中测试Quantopticon强大的仿真软件的应用，使其更快，更有效地工作，并为其提供用户友好的界面。我们将证明该软件可能会在技术上重要的领域产生影响。我们的仿真工具将消除进行多个昂贵的实验的需求，从而极大地加速和优化氮化物QD设备的设计和制造。
