利用弱测量技术研究两量子比特的量子关联动力学演化和转移。有纠缠突然死亡现象产生的非最大纠缠初态经前选择测量操作后，在演化过程中不但能够提高量子关联强度，而且能够缩短甚至消除量子比特纠缠的突然死亡区域；而对于演化中无纠缠突然死亡的非最大纠缠初态，弱测量操作则会降低量子比特间关联强度。对初始处于最大纠缠态的粒子，弱测量操作不能增强粒子间的纠缠但可以优化量子关联中的量子失谐。弱测量在实现量子关联转移时的破坏极小，能够延迟纠缠的衰减，并可使量子纠缠的转移时间提前。另外腔场与量子比特间的耦合强度与系统耗散率的关系决定纠缠原子在腔中动力学演化，表现为马尔可夫和非马尔可夫过程。

Dynamics evolution of quantum correlation of two entangled qubits is investigated by using the techniques of weak measurement. The initial non-maximally entangled particles with entanglement sudden death happening are operated by pre-selection measurement, which not only improve the quantum correlations, but also can reduce or even eliminate entanglement sudden death region; As for the evolution of non-maximally entangled initial state without entanglement sudden death, the weak measurement will degrade the intensity of quantum correlation of qubits. The operation of weak measurement can not enhance entanglement between particles but can optimize quantum discord when particles are initially in maximally entangled state. Weak measurement has little effect on the quantum correlation transfer procession and can postpone the decay of entanglement, and even can make entanglement transfer happen earlier. In addition, the relation of system dissipation rate and coupling strength between the cavity field and qubits can also affect its dynamical evolution, showing Markov and non-Markov processes.
