The study of optical modes carrying low-order states of orbital angular momentum (OAM) in fiber during the last decade was motivated by the paradigm-changing potential for optical communication applications in terms of enhanced information capacity. However the latest research shows that new scientific and technological advances in the area will depend on our ability to harness the high-order OAM modes. These high-order OAM modes have started to open an even larger unexplored world of fundamental discoveries through the study of high-dimensional quantum states of light. The proposed research program is expected to provide new fundamental insights into quantum light-matter interactions and push the scientific frontiers of quantum communications and quantum sensing. This will be achieved through: 1) finding new optical fibers and photonic schemes to access the high-order OAM modes, 2) the investigation of new methods and techniques for high-dimensional quantum OAM communications, and 3) the study of new modalities for fiber-optic quantum sensing using diamond NV centers.      Owing to the rapidly growing interest in quantum technologies at all levels of the academic, public and private sectors, there is a fertile ground for scientific contributions coming from the proposed program. Research in a future quantum connected world lies at the intersection of electrical engineering, information science and physics. It is thus crucial and urgent to establish a diverse workforce skilled in handling these complex quantum systems through graduate research training. Hence another key outcome of this program is the training of the next-generation of scientists in the fields of quantum information science and quantum metrology. The new methods, know-how and HQP produced in Canada through this program will promote further scientific advances in the domain and feed this emerging R&D ecosystem of strategic importance to our collective future.

过去十年中，对光纤中携带轨道角动量（OAM）低阶态的光学模式的研究是受到光通信应用在增强信息容量方面的范式改变潜力的推动。然而，最新研究表明，该领域的新科学技术进步将取决于我们利用高阶 OAM 模式的能力。通过对光的高维量子态的研究，这些高阶 OAM 模式已经开始打开一个更大的未探索的基本发现世界。拟议的研究计划预计将为量子光与物质相互作用提供新的基本见解，并推动量子通信和量子传感的科学前沿。这将通过以下方式实现：1) 寻找新的光纤和光子方案来访问高阶 OAM 模式，2) 研究高维量子 OAM 通信的新方法和技术，以及 3) 研究使用金刚石 NV 中心的光纤量子传感新模式。      由于学术、公共和私营部门各个层面对量子技术的兴趣迅速增长，拟议项目为科学贡献提供了肥沃的土壤。未来量子互联世界的研究处于电气工程、信息科学和物理学的交叉点。因此，通过研究生研究培训建立一支能够熟练处理这些复杂量子系统的多元化劳动力队伍至关重要且紧迫。因此，该计划的另一个关键成果是在量子信息科学和量子计量领域培训下一代科学家。加拿大通过该计划产生的新方法、专有技术和总部将进一步促进该领域的科学进步，并为这个对我们共同的未来具有战略重要性的新兴研发生态系统提供支持。
