Abstract

The effect of environment-assisted measurement and quantum measurement reversal on the entanglement transfer in two parallel Heisenberg spin chains is investigated. We derive the exact analytical expression of the optimal final restoration, show that the distribution entanglement could be restored to the initial value, which is independent of the size of the spin chain. Comparing with the results obtained by the method of weak measurement, our results show notable superiorities on restoration scope and success probability.

在两条平行海森堡自旋链中通过环境辅助测量和量子测量反转恢复纠缠传递

我们研究了环境辅助测量和量子测量反转对两条平行海森堡自旋链中纠缠转移的影响。我们推导出了最优最终恢复的精确分析表达式，证明了分布纠缠可以恢复到初始值，且与自旋链的大小无关。与采用弱测量方法得出的结果相比，我们的结果在还原范围和成功概率上都有显著优势。
