In this paper, the dynamics of quantum correlation quantified by local quantum uncertainty (LQU) and local quantum Fisher information (LQFI) for two uncoupled qubits driven by classical phase noisy laser have been investigated. The results show that, both LQU and LQFI exhibit similar behaviours, either display exponential decay or oscillatory decay with revivals depending on the ratios of classical phase noisy laser rate and system-environment coupling strength. Beside, our results also confirm the amount of quantum correlation measured by LQU is strictly bounded by LQFI in an open system. Finally, we propose a scheme to protect quantum correlation against classical phase noisy laser with the technique of weak measurement and reversal.

本文研究了由经典相位噪声激光器驱动的两个非耦合量子位的由局部量子不确定性（LQU）和局部量子Fisher信息（LQFI）量化的量子相关动力学。结果表明，LQU和LQFI都表现出相似的行为，表现出指数衰减或振荡衰减，并随着经典相位噪声激光速率与系统-环境耦合强度之比的增加而恢复。此外，我们的结果还证实，在开放系统中，由LQU测量的量子相关量受LQFI严格限制。最后，我们提出了一种利用弱测量和反向技术来保护量子相关性免受经典相位噪声激光侵害的方案。
