论文摘要
通过考虑在存在内在的脱附存在下由Heisenberg各向异性相互作用描述的两个相互作用的自旋1/2量子A的确切可解决的模型，我们研究了基于Hilbert-Schmidt Norm和不同初始条件的同意和测量诱导的非局部性（Min）量化的纠缠动态。我们强调了纠缠和最小初始状态的最小关系之间的关系。对于初始可分离状态，发现稳健性和量子相关的产生取决于物理参数。在将纠缠状态视为初始状态的同时，结果表明，尽管相位的相位相位，但在表现出一些振荡后，所有相关都达到其稳态值。最后，我们表明，在未进入状态下，最低捕获的量子相关的存在。
By considering an exactly solvable model of a two interacting spin-1/2 qubits described by the Heisenberg anisotropic interaction in the presence of intrinsic decoherence, we study the dynamics of entanglement quantified by the concurrence and measurement-induced nonlocality (MIN) based on Hilbert-Schmidt norm and trace distance with different initial conditions. We highlight the relationship between the entanglement and MIN for the pure initial state. For an initial separable state, it is found that the robustness and the generation of the quantum correlations depend on the physical parameters. While considering the entangled state as an initial state, the results show that despite the phase decoherence all the correlations reach their steady state values after exhibiting some oscillations. Finally, we show that the existence of quantum correlation captured by MIN in the unentangled state.
