Quantum mechanics can provide the solution for unbreakable communications (e.g., a network with absolute security for financial transactions, medical and personal records etc.) and powerful computing (e.g., a platform capable of quickly processing huge sensory data). However, the realization of non-classical systems remains challenging as it pushes the limits of current technology in terms of scalability, stability and power consumption. The competing approaches (using ion traps, spintronics, electrons etc.) suffer from a high-cost, bulk scale and/or the need for operation under lab-controlled conditions, dramatically restricting the accessible computational resources and ultimately, the potential for real-world applications. Integrated photonics is increasingly perceived as a practical, scalable platform for implementing quantum technology, as it has the key advantages of being compatible with fiber-optic communication networks as well as with silicon electronics. However, current on-chip quantum circuits generate and efficiently process only qubits (i.e. two-dimensional states), with a footprint exponentially increasing with the problem complexity. In this project, university researchers from INRS-EMT, working in close collaboration with their industrial partners (OptoElectronics Components, and QPS Photronics in Canada), will develop a novel, robust, stable, and relatively low-cost platform for on-chip generation, manipulation and processing of optical quDits (i.e. high-dimensional states), with capabilities consistent with practical applications in communications, computing, sensing etc. In particular, our scheme will be based on on-chip optical frequency combs and the use of widely accessible fiber-optic signal processing techniques. We will target the demonstration of applications of the developed platform for high-bit-rate quantum random number generation, and fiber-based sensing with quantum-enhanced sensitivity, in line with the specific interests of our industrial partners. The know-how and technology to be generated from our project and the training of highly-qualified personnel will place Canada in a leading position in both the photonics and quantum fields.************

量子力学可以为牢不可破的通信提供解决方案（例如，为金融交易、医疗和个人记录等提供绝对安全的网络）和强大的计算（例如，能够快速处理大量传感数据的平台）。 然而，非经典系统的实现仍然具有挑战性，因为它推动了当前技术在可扩展性，稳定性和功耗方面的限制。竞争的方法（使用离子阱，自旋电子学，电子等）。受到高成本、大规模和/或需要在实验室控制条件下操作的困扰，极大地限制了可访问的计算资源，并最终限制了现实世界应用的潜力。集成光子学越来越被认为是实现量子技术的实用、可扩展的平台，因为它具有与光纤通信网络以及硅电子兼容的关键优势。然而，当前的片上量子电路仅生成并有效地处理量子比特（即二维状态），其占用空间随着问题的复杂性呈指数级增加。在这个项目中，来自INRS-EMT的大学研究人员与他们的工业合作伙伴密切合作，（OptoElectronicsComponents和加拿大的QPSPhotronics）将开发一种新颖、坚固、稳定和相对低成本的平台，用于光量子的片上生成、操纵和处理。（即，高维状态），具有与通信、计算、传感等中的实际应用一致的能力。我们的方案将基于片上光频梳和使用广泛可获得的光纤信号处理技术。我们将针对高比特率量子随机数生成平台的应用演示，以及具有量子增强灵敏度的光纤传感，符合我们工业合作伙伴的具体利益。我们的项目所产生的知识和技术以及高素质人才的培训将使加拿大在光子学和量子领域处于领先地位。
