Quantum networks can provide a revolutionary solution to our society's need for secure communication, as required, e.g., in the transmission of personal, bank, and government data. A quantum communication network consists of integrated local nodes allowing the generation of optical quantum states through single- and two-photon entangled sources, as well as their long-term storage through quantum memories. Photons are then shared among distant partners through a fiber-optic infrastructure connecting the local quantum nodes. Several approaches have been explored to realize integrated local nodes; quantum dots for single-photon sources, Chi(3) materials (e.g., Hydex glass) for two-photon sources, and spin-active impurities for quantum memories. However, two main bottlenecks prevent the development of quantum networks: (i) photon losses and (ii) the lack of a robust interconnection between the local nodes. The only way to achieve long-distance quantum communications is to minimize optical losses stemming from the network components. In this proposal, the PI aims, with the support of the industrial partner OEC, to develop low-loss and robust interconnects between integrated waveguide-based photonic chips and standard optical fibers, a crucial milestone towards the commercialization of fiber-based quantum secure communications. To this end, we will deliver (I) a microring resonator capable of generating high-dimensional frequency entangled photon pairs with novel enhanced coupling efficiency and performances, (II) low-loss photon processing schemes based on off-the-shelf fiber-based components, and (III) superconducting nanowire single-photon detectors with high-detection efficiency and optimized for coupling to different material platforms. This proposal features an extensive collaboration with UK academic and industrial teams, who will develop in parallel SiN-based photonics chips, as well as photon emitters and quantum memories. The targeted outcomes will benefit Canadian industry through the training of highly qualified personnel in the fields of integrated photonics and device design and will contribute to maintain Canada as a leading player in the quantum secure communication market.

量子网络可以为我们社会对安全沟通的需求提供革命性的解决方案，例如在个人，银行和政府数据的传输中。量子通信网络由集成的本地节点组成，允许通过单光和两光纠缠来源产生光学量子状态，以及它们通过量子记忆的长期存储。然后，通过连接局部量子节点的光纤基础结构在遥远的伴侣之间共享光子。已经探索了几种方法来实现集成的本地节点。单光子源，CHI（3）材料（例如，Hydex玻璃）的量子点，用于两光子源的材料以及用于量子记忆的旋转杂质。但是，两个主要的瓶颈阻止了量子网络的发展：（i）光子损失和（ii）局部节点之间缺乏稳健的互连。实现长距离量子通信的唯一方法是最大程度地减少来自网络组件的光损失。在该建议中，PI的目标是在工业合作伙伴OEC的支持下，在基于波导的光子光子芯片和标准光纤之间发展低损失和稳健的互连，这是基于纤维的量子量安全通信的关键里程碑。为此，我们将提供（i）一个微孔谐振器，能够生成高维频率纠缠的光子对，并具有新颖的增强的耦合效率和性能，（ii）基于基于现成的纤维组件的低损耗光子处理方案，（III）超级导向材料与高点效率和高点效率相同，以实现材料效率和高点效率。该提案与英国学术和工业团队进行了广泛的合作，他们将以平行的基于罪的光子芯片以及光子发射器和量子记忆发展。有针对性的结果将通过在集成光子学和设备设计领域培训高素质的人员，从而使加拿大行业受益，并将为维持加拿大作为量子安全通信市场的领先参与者做出贡献。
