NEXUS-QP

计算、通信、图像和传感的单独数字技术，当它们连接在一起并共同工作时，可以提供更强大的服务。同样，如果我们能够将不同的量子技术连贯地连接在一起，这些不同的量子技术正在朝着更快的计算、更安全的通信和更高精度的传感方向发展，那么一套更全面的能力将被实现。此外，为了充分发挥量子计算机的潜力，量子计算机必须被设计和建造为一种由相干连接的模块组成的体系结构。由量子计算机、量子传感器和量子通信模块组成的相干连接网络将为社会带来变革性的好处。在医疗保健领域，量子设备网络可以帮助个人私下监控自己的健康状况，同时实现安全、高效和个性化的药物设计。在清洁能源领域，聚变反应堆的海量数据可以被快速监测，以维持能源供应，而对其核物理进行并行实时建模可能会增加能源产生。要将这一愿景变成现实，需要在低温恒温器内连贯地连接通常处理量子信息的硬件模块。这包括将实现大面积量子网络的量子中继器模块。然而，稳健地向/从低温恒温器输入/输出量子信息，从而使其能够与其他高保真的低温恒温器连接，是具有挑战性的。此外，使用标准的导热电子线路输入/输出相对较大的经典控制和读出数据集是困难的，因为标准导热电子线路将低温恒温器的内部连接到外部世界。二元量子光子公司(DQP)正在开发的技术为这些挑战提供了强大的解决方案。在这个项目中，DQP将开发其Nexus量子光子学(Nexus-QP)芯片组，以连贯地连接不同的低温恒温器。Nexus-QP将共集成组件，以产生、处理和检测光的量子态，产生和检测同向传播的经典控制激光，执行快速光子开关，并支持低损耗光纤连接以实现对低温恒温器的光学访问，减少热负载。NEXUS-QP将使位于同一地点(相同房间/建筑)或地理分布(例如不同城市)的低温恒温器网络之间能够交换量子信息和经典控制信号。DQP将与国内和国际领先的技术公司合作，帮助指导产品开发，利用其英国制造基地制造适合大规模生产的光子芯片组件和系统，并最终帮助提供国家和全球量子网络。

Individual digital technologies that compute, communicate, image, and sense, deliver an altogether more powerful service when they are connected and work together. Similarly, a more comprehensive set of capabilities will be realised if we can coherently network the different quantum technologies that are individually progressing toward faster computing, securer communications, and higher precision sensing. Additionally, to meet their full potential, quantum computers must be designed and constructed as an architecture of modules that are coherently connected.A coherently connected network of quantum computers, quantum sensors, and quantum communication modules will provide transformative benefits for society. In healthcare, a network for quantum devices could help individuals privately monitor their health while enabling secure, efficient and personalised drug design. In clean energy, massive data from fusion reactors could be rapidly monitored to maintain energy availability, while in-parallel real-time modelling of their nuclear physics could increase energy generation.Turning this vision into a reality requires technology to coherently connect hardware modules that typically process quantum information at extremely low temperatures, inside a cryostat. This includes the _quantum repeater_ modules that will enable large area quantum networks. However, robustly inputting/outputting quantum information to/from a cryostat such that it can be connected to other cryostats with high fidelity, is challenging. Additionally, inputting/outputting relatively large sets of classical control and readout data is difficult with standard thermally conductive electronic wiring, which interfaces the inside of a cryostat to the outside world.The technology being developed by Duality Quantum Photonics (DQP) offers a powerful solution to these challenges. In this project, DQP will develop its NEXUS Quantum Photonics (NEXUS-QP) chipset to coherently connect different cryostats. NEXUS-QP will co-integrate components to generate, process, and detect quantum states of light, to generate and detect co-propagating classical control laser light, to perform fast photonic switching, and to support low-loss optical fibre connections for optical access to cryostats reducing the thermal load.NEXUS-QP will enable the exchange of quantum information and classical control signals among a network of cryostats that are co-located (same room/building) or geographically distributed (e.g. different cities). Working with leading national and international technology companies to help guide product development, DQP will use its UK fabrication site to manufacture components and systems in photonic chips that are suitable for mass scaling and will ultimately help deliver a national and global quantum network.
