AI 中文摘要
我们研究了通过电磁力相互作用的两个谐波捕获电子之间的量子纠缠动力学。从热平衡下的双模高斯态出发，利用协方差矩阵形式来计算演化态的对数负性作为纠缠的定量度量。分析了两种初始配置：热单模和双模压缩态，并描述了不同压缩和温度值下系统中纠缠的时间演化，同时确定了当前和近期单电子陷阱实验可及的参数范围。
英文摘要
We study the dynamics of quantum entanglement between two harmonically trapped electrons interacting via the electromagnetic force. Starting from two-mode Gaussian states at thermal equilibrium, we make use of the covariance matrix formalism in order to compute the logarithmic negativity of the evolved state as a quantitative measure of entanglement. We analyze two initial configurations: thermal single-mode and two-mode squeezed states, and describe the time evolution of entanglement in the system for different values of squeezing and temperature, while identifying the parameter regimes accessible to current and near-future single-electron trap experiments.
