Nonlinear Quantum Control Engineering

本项目将在量子风险敏感控制方法和经典非线性控制方法的基础上，开发可处理的鲁棒、非线性、相干反馈控制系统的设计方法。它还将开发用于非线性和有限能级量子系统的鲁棒非线性滤波器和相干观测器的设计方法，并将这些结果应用于基于鲁棒测量的量子控制器的设计。此外，该项目将应用相干和基于测量的鲁棒控制方法来实现非线性量子网络中有用的突发行为。这种涌现行为可能涉及退相干效应的鲁棒减少和量子计算问题的鲁棒解决。

This project will develop tractable methods for the design of robust, nonlinear, coherent feedback control systems building on the approach of quantum risk sensitive control and extending classical nonlinear control methods. It will also develop methods to design robust and nonlinear filters and coherent observers for nonlinear and finite level quantum systems and apply these results to the design of robust measurement based quantum controllers. In addition, the project will apply coherent and measurement based robust control methods to achieve useful emergent behaviours in nonlinear quantum networks. Such emergent behaviours may involve the robust reduction of decoherence effects and the robust solution of quantum computational problems.
