摘　　要：本文研究了Markovian过程和non-Markovian过程两种情况下,原子系统中偶极-偶极(D-D)相互作用和失谐量对两原子系统量子存储支撑(QMA)熵不确定度的调控作用.与Markovian过程相比,在non-Markovian过程中,由于库环境的记忆效应使得具有D-D相互作用的两原子系统QMA熵不确定度的演化行为呈现出振荡上升现象,且熵不确定度的上升趋势得到减缓,从而抑制了由系统量子噪声引起的退相干效应.此外,D-D相互作用对两原子系统QMA熵不确定度具有显著的调控能力,且D-D相互作用比失谐量的调控能力更强.In this paper,we have investigated the controlling of the dipole-dipole(D-D)interaction and detuning amount on the quantum memory assisted(QMA)entropy uncertainty of the two-atom system in Markovian and non-Markovian processes.It is found that the memory effect of the reservoir environment causes the dynamical behaviour of the QMA entropy uncertainty of the two-atom system to show a phenomenon of oscillation,the rising trend of the QMA entropy uncertainty is slowed down,and it can suppress the decoherence effect of the system caused by quantum noise in the non-Markovian process.In addition,the D-D interaction has significant control ability to reduce the QMA entropy uncertainty and it has stronger control ability than the detuning amount.
