原子系统中偶极-偶极相互作用对量子存储支撑熵不确定度的调控研究

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.

The Controlling of the Dipole-Dipole interaction on the Quantum Memory Assisted Entropy Uncertainty of atom systems

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.
