论文摘要
在本文中,我们利用不同的量子度量概念来理解有和没有PT对称操作的Heisenberg XY模型的性质。在没有PT对称性的情况下,我们研究了不同度量的重要性,即纠缠和测量引起的非局部性(min),在检测海森堡XY模型的量子性时。据观察,量子相关性和传送忠诚度相对于温度单调降低。此外,PT对称操作的干预增强了量子相关的强度。此外,我们强调了系统参数的作用和PT对称操作在量子状态的传送中。我们的结果还强调,在添加PT对称操作后,所考虑的物理模型仍然是成功接近量子状态的通用资源。
In this article, we exploit the different notions of quantumness measure to understand the properties of the Heisenberg XY model with and without PT-symmetric operation. In the absence of PT-symmetry, we study the significance of different measures, namely entanglement and measurement induced nonlocality (MIN), in the detection of the quantumness of the Heisenberg XY model. It is observed that the quantum correlations and teleportation fidelity monotonically decreases with respect to temperature. Furthermore, the intervention of PT-symmetric operation enhances the strengths of quantum correlation. In addition, we highlight the role of the system's parameters and PT-symmetric operation on the teleportation of a quantum state. Our results also emphasize that after the addition of PT-symmetric operation, the considered physical model remains a versatile resource to achieve successful teleportation of the quantum state.
