Directly-written integrated photonic circuits for quantum dot-based quantum simulations

Tom Street将在模块化、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。这些小簇将通过极化编码纠缠在一起。这种微型簇态将被输入到他将在麦考瑞大学制造的直接写入波导电路中，这种电路是以前为量子随机漫步（QRWs）设计的，并且需要保持极化。QWR电路中3-6个光子微团簇的处理将导致复杂多体态的产生，这可能被设计成映射到其他物理领域的多体问题，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负责当地监督。

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.
