n开放量子系统是与外部环境或浴室相互作用的量子系统。系统与浴室之间的相互作用通常太复杂,无法准确模拟,因此需要近似模拟才能平均浴室的效果,这导致了开放量子系统的非单身动力学。模拟量子系统的动力学一直是量子计算研究的主要重点,1-6但已经开发了相对较少的量子算法来模拟开放量子系统的动力学。7 - 16到这一目标,我们已经开发并展示了一种开放量子动力学17-19的通用量子算法,该算法能够模拟一般和复杂的物理系统。量子算法利用SZ.-NAGY单一扩张方法将非单身时间演化运算符转换为相应的单一操作员,然后可以在量子电路上实现。This quantum algorithm has been applied to a variety of physical systems, including the amplitude damping channel described by the Kraus representation, 17 the Jaynes − Cummings model described by the Kraus representation, 20 the Fenna − Matthews − Olson (FMO) complex described by the Lindblad master equation, 18 and the spin-boson model described by the generalized quantum master equation (GQME).19
