An ideal single-photon source will produce a single-photon triggered by the push of a button. Remarkable progress has been made in recent years to the point where photons from such sources can be delivered to an end user with a probability exceeding 50%. The downside to current state of the art single-photon source technology is the high barrier to entry: sources are triggered by pulsed laser systems, operate at cryogenic temperatures, and frequently require employment of specialist staff all of which exacerbates costs. The result is that for many applications, potential users opt for simpler and more cost-effective probabilistic sources, where the single photon probability is capped at <10%.COMPHORT tackles this challenge by developing a user-friendly "plug & play" device that will feature single-photon generation probabilities exceeding 80% without requiring bulky laser systems or cryogenics. To achieve this, we take advantage of the exceptional optical properties of single photons generated by quantum emitters in hexagonal boron nitride, when operated under ambient conditions (20 degC). We will then enhance this by directly integrating emitters into bespoke open optical cavities, which will be packaged into a robust assembly to provide reliable operation. Further, a pump LED will be monolithically integrated into our open cavity design to trigger single-photon emission, providing the end user with a simplified electrically driven device. Both the quantum emitters and optical cavity can be engineered to suit a range of quantum applications (from communications to metrology or imaging). To showcase the suitability of our technology for real-world applications, we will implement free-space quantum communication protocols at the laboratory-scale and in a metropolitan free-space link in Berlin city. This quantum application is crucial to interconnect networks where optical fibers are not available (such as disaster zones, or field hospitals) and/or a changing geo-localisation between nodes is required (autonomous car, aeroplanes, drones, etc). The project will develop in close collaboration with the SME partners Nanoplus GmbH and QLocked, bridging the connection between our technology outcomes and the quantum photonics market. The outputs of COMPHORT are aimed at providing Europe with a valuable sovereign technology in an increasingly competitive quantum-enabled world economy

理想的单光子源将产生由按钮的按钮触发的单光子。近年来，已经取得了显着的进展，直到可以将来自此类来源的光子传递给最终用户，概率超过50％。当前最先进的单光子源技术的缺点是进入的高障碍：来源是由脉冲激光系统触发的，在低温温度下运行，并且经常需要雇用专家工作人员，所有这些都加剧了费用。结果是，对于许多应用程序，潜在的用户选择更简单，更具成本效益的概率来源，其中单个光子概率被限制在<10％的范围内。Comphort通过开发一个将具有超过80％超过80％不需要繁重的Laser Systems或Cryegogogogogogogogeny的用户友好的“插件和游戏设备）来应对这一挑战。为此，当在环境条件下（20 degc）操作时，我们利用量子发射器在六角硼硼中产生的单个光子的非凡光学特性。然后，我们将通过将发射器直接集成到定制的开放光腔中来增强此功能，该光腔将包装到健壮的组件中以提供可靠的操作。此外，LED将单层整合到我们的开放式腔设计中，以触发单光子发射，从而为最终用户提供了简化的电气驱动设备。量子发射器和光腔都可以设计用于适合一系列量子应用（从通信到计量或成像）。为了展示我们技术对现实世界应用的适用性，我们将在实验室规模和柏林市的大都市自由空间链接中实施自由空间量子通信协议。此量子应用对于不可用的光纤（例如灾难区或野外医院）和/或节点之间不断变化的地理位置化（自动驾驶汽车，飞机，无人机等）之间的量子应用至关重要。该项目将与SME Partners Nanoplus GmbH密切合作开发并进行了Qlock，从而弥合了我们的技术成果与量子光子市场之间的联系。 Compant的产出旨在为越来越具有竞争力的量子经济提供欧洲提供宝贵的主权技术
