In the context of major technological advances, smart applications, and an increased amount of data transmitted over the internet, the need for trusted data security approaches has never been more pressing. This requires high levels of computational complexity through traditional methods, and given the scalability limits of electronic devices, novel countermeasures are much in demand. A promising approach for secure communication is provided by quantum cryptography (QC), a revolutionary method which uses the quantum features of particles for data encryption, by means of quantum key distribution (QKD). Photonic platforms provide huge advantages in terms of speed, transmission distance, and encoding techniques, as well as device footprint and power consumption. These are only made possible via integration strategies of on-chip structures with fiber-optic networks. However, the development of such devices for real-world implementations often dictates a trade-off between cost and performance. In the proposed project, we aim, with the support of our industrial partner OEC, to achieve three primary objectives: i) realization of efficient source (micro-resonator) cavity architectures for the generation of classical and quantum light; ii) quantification of source properties such as efficiency, coherence, etc. and the implementation of standard QKD protocols using the proposed source architectures; and iii) development of an optimized and compact all-fiber prototype for commercialization. The envisioned platform will utilize the temporal modes of photons for encryption, scalable to other degrees of freedom. This proposal benefits from the successful collaboration with the UK academic and industrial teams, who will, in parallel, realize such source architectures for the development of miniature atomic clocks. The project outcomes will benefit Canada through the training of highly qualified personnel in the interdisciplinary fields of integrated photonics and device design, thus allowing them to pursue careers in both industry and academia. The development of state-of-the-art quantum technologies is key to maintaining Canada's edge in information technology and quantum communication applications.

在重大技术进步，智能应用程序以及通过Internet传输的数据增加的背景下，对受信任的数据安全方法的需求从未如此紧迫。这需要通过传统方法高水平的计算复杂性，并且鉴于电子设备的可伸缩性限制，新颖的对策需求量很大。量子密码学（QC）提供了一种有希望的安全通信方法，这是一种革命性方法，它通过量子键分布（QKD）使用粒子的量子特征进行数据加密。光子平台在速度，传输距离和编码技术以及设备足迹和功耗方面具有巨大的优势。这些仅通过与光纤网络的片结构的集成策略来实现。但是，用于现实世界实施的这种设备的开发通常决定成本和绩效之间的权衡。在拟议的项目中，我们的目标是在我们的工业合作伙伴OEC的支持下实现三个主要目标：i）实现有效源（微谐波）腔体体系结构，以生成古典和量子光； ii）使用拟议的源体系结构量化源属性，例如效率，连贯性等以及实施标准QKD协议； iii）开发优化和紧凑的全纤维原型，用于商业化。设想的平台将利用光子的时间模式进行加密，可扩展到其他自由度。该建议受益于与英国学术和工业团队的成功合作，他们将同时实现这种源体系结构来开发微型原子钟。该项目成果将通过在综合光子学和设备设计的跨学科领域中培训高素质的人员，从而使加拿大受益，从而使他们能够从事行业和学术界的职业。最先进的量子技术的开发是维持加拿大信息技术和量子通信应用程序优势的关键。
