摘要

提出了一种实时反馈控制方案,以确定性地产生两个部分分离原子的最大纠缠贝尔态。最近引入的SWM-(同时弱测量)诱导量子态约简的概念推广到反对易观测的情况。这种推广使得贝尔态的概率准备可以通过一个线性可观测值和一个非局部可观测值的swm来实现。然后通过将swm诱导的量子态还原与反馈控制相结合来实现所需贝尔态的确定性生成。采用时滞控制方法,通过控制输入的时滞补偿基于滤波器的控制的计算时间,保证了控制方案的实时性。

Realtime generation of the bell states by linear-nonlocal measurements and bang-bang control
We present a realtime feedback control scheme to deterministically produce the maximally entangled Bell states of two partially separated atoms. The recently introduced concept of SWM- (simultaneous weak measurements)-induced quantum state reduction is generalized to the case of anti-commutative observables. This generalization enables the probabilistic preparation of the Bell states via the SWMs of one linear observable and one nonlocal observable. The deterministic generation of the desired Bell state is then carried out by combining SWM-induced quantum state reduction with feedback control. The realtime implementation of the proposed control scheme is guaranteed by using the time delay control approach in which the computation time of filter-based control is compensated for by the delay time in control input.
