论文摘要
光学量子技术有望改变当今的信息处理和传感器。对许多量子应用至关重要是纯单光子的有效来源。为了使量子发射极用于这种应用，或者要彼此耦合不同的量子系统，需要定制量子发射极的光发射波长。在这里，我们使用密度功能理论来计算和操纵二维材料二维型氮化硼中荧光缺陷的过渡能。我们的计算具有HSE06功能，该功能使我们能够准确预测267个不同缺陷的电子带结构。此外，使用应变调节我们可以调整合适的量子发射器的光学过渡能，以与量子技术应用相匹配。因此，我们不仅提供了为特定应用程序制作发射器的指南，而且还提供了一个有希望的量子量子发射器的途径，这些量子发射器可以将其搭配到其他固态Qubit系统（例如Diamond的颜色中心）。
Optical quantum technologies promise to revolutionize today's information processing and sensors. Crucial to many quantum applications are efficient sources of pure single photons. For a quantum emitter to be used in such application, or for different quantum systems to be coupled to each other, the optical emission wavelength of the quantum emitter needs to be tailored. Here, we use density functional theory to calculate and manipulate the transition energy of fluorescent defects in the two-dimensional material hexagonal boron nitride. Our calculations feature the HSE06 functional which allows us to accurately predict the electronic band structures of 267 different defects. Moreover, using strain-tuning we can tailor the optical transition energy of suitable quantum emitters to match precisely that of quantum technology applications. We therefore not only provide a guide to make emitters for a specific application, but also have a promising pathway of tailoring quantum emitters that can couple to other solid-state qubit systems such as color centers in diamond.
