论文摘要
在存在环境的情况下,针对海森贝格XYZ自旋系统研究了两分状态(超越纠缠)的量子相关性。结果表明,如果允许系统与环境交换能量,则初始状态会在渐近极限下进化并沉降到不相关的状态。我们还证明,基于保真度的测量引起的非局部性是表征相关量子状态的有用数量。
Quantum correlation of bipartite states (beyond entanglement) in presence of environment is studied 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 measurement induced non-locality is a useful quantity in characterizing correlated quantum states.
