Harnessing the quantum mechanical properties of light is an appealing approach to developing future quantum technologies for applications in communications, sensing, simulation and computation. Integrated quantum photonics waveguide circuits and orbital angular momentum are two promising but disparate fields of quantum photonic research that hold great potential for the development of future quantum photonic technologies. Integrated quantum photonic (IQP) waveguide circuits control and manipulate light propagating within mm-sized waveguide circuits, whereas the orbital angular moment (OAM) degree-of-freedom of the photon enables efficient communication of quantum information through the generation of high-dimensional entangled qu-dits propagating in free-space.This research project aims to merge these two seemingly incompatible technologies to realised integrated quantum photonic waveguide circuits that can generate, manipulate and detect OAM states of light for chip-to-chip transfer of quantum information. This new integration technology will harness the advantages of both IQP and OAM to develop new applications in quantum communications, distributed quantum information processing, generation of high-dimensional entanglement and hyper-entanglement, quantum key distribution and the investigation of fundamental science.

利用光的量子力学特性是开发未来量子技术用于通信，传感，模拟和计算的一种有吸引力的方法。集成量子光子学波导电路和轨道角动量是量子光子学研究的两个有前途但不同的领域，对未来量子光子技术的发展具有巨大的潜力。集成量子光子（IQP）波导电路控制和操纵在mm尺寸的波导电路内传播的光，而光子的轨道角动量（OAM）自由度通过产生在自由空间中传播的高维纠缠量子点来实现量子信息的有效通信。该研究项目旨在将这两种看似不兼容的技术合并，以实现集成量子光子波导电路，操纵和检测光的OAM状态，用于量子信息的芯片到芯片传输。这种新的集成技术将利用IQP和OAM的优势，在量子通信，分布式量子信息处理，高维纠缠和超纠缠的产生，量子密钥分配和基础科学研究中开发新的应用。
