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.

量子力学可以为无法破坏的通信提供解决方案（例如，具有绝对安全性的用于金融交易，医疗和个人记录等的网络）和强大的计算（例如，一个能够快速处理大量感官数据的平台）。 但是，非古典系统的实现仍然具有挑战性，因为它在可扩展性，稳定性和功耗方面推动了当前技术的极限。竞争方法（使用离子陷阱，旋转型，电子等）遭受了高成本，批量规模和/或在实验室控制条件下进行操作的需求，从而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。综合光子学越来越被视为实施量子技术的实用，可扩展的平台，因为它具有与光纤通信网络以及硅电子产品兼容的关键优势。但是，当前的芯片量子电路会生成有效地处理Qubit（即二维状态），并且足迹成倍地随问题的复杂性而呈指数增长。 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特别是，我们的方案将基于片上光学频率梳子和广泛访问的光纤信号处理技术的使用。我们将针对开发平台的高位量子量子随机数生成的应用，并以量子增强的灵敏度为基础，符合我们工业伙伴的特定利益。我们的项目和高度合格人员的培训将在光子学和量子场领域的领先地位。
