Quantum correlation of bipartite states (beyond entanglement) in presence of environment is studied using measurement-induced nonlocalities (MINs) for Heisenberg $XYZ$ spin system. It is shown that if the system is allowed to exchange energy with environment, the initial state evolves and settles down to uncorrelated state in asymptotic limit. We have also demonstrated that fidelity based MIN is sensitive to such open system, and so useful for characterizing the correlation of the states.

海森堡XYZ自旋模型中环境对量子相关性的影响

使用 Heisenberg 的测量诱导非定域性 (MIN) 研究存在环境时二分状态（超越纠缠）的量子相关性 $X是Z$自旋系统。结果表明，如果允许系统与环境进行能量交换，则初始状态会在渐近极限内演化并稳定到不相关状态。我们还证明了基于保真度的 MIN 对这种开放系统很敏感，因此对于表征状态的相关性非常有用。
