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 将在模块化、可扩展的平台中开发小型（3-6 个光子）光子迷你簇态的量子点 (QD) 源。这些微型团簇将通过偏振编码纠缠在一起。微型簇态将被输入到他将在麦考瑞大学制造的直写波导电路中，该电路是先前为量子随机游走（QRW）设计的类型，并且需要偏振保持。 QWR 电路中 3-6 个光子微型团簇的处理将产生复杂的多体态，这些态可以被设计为映射到其他物理领域的多体问题，从而实现量子模拟。这是与麦考瑞大学合作的一个 cotutelle 项目，由物理系的 Mike Steel 进行当地监督。
