Tom Street will develop a quantum dot (QD) source of small (3-6 photon) photonic mini-cluster states in a modular, scalable platform. These mini-clusters will be entangled via polarization encoding. The mini-cluster states will be fed into a directly-written waveguide circuit that he will fabricate at Macquarie University, of the type designed previously for quantum random walks (QRWs), and required polarization preservation. The processing of the 3-6 photon mini-clusters in the QWR circuit will result in the production of complex multi-body states which may be engineered to map onto many-body problems in other areas of physics, thus enabling quantum simulations. This is a cotutelle project with Macquarie University, with local supervision undertaken by Mike Steel in the Dept of Physics.

Tom Street将在一个模块化、可扩展的平台上开发一个小（3-6个光子）光子微簇态的量子点（QD）源。这些小团簇将通过偏振编码纠缠在一起。微型团簇状态将被馈送到他将在麦考瑞大学制造的直接写入波导电路中，该电路是以前为量子随机行走（QRW）设计的类型，并且需要保持偏振。在QWR电路中处理3-6个光子微型团簇将导致产生复杂的多体状态，这些状态可以被设计成映射到物理学其他领域的多体问题，从而实现量子模拟。这是一个与麦考瑞大学合作的项目，由物理系的Mike Steel进行当地监督。
