论文摘要
在这项工作中，我们将研究局部量子Fisher信息和在Z方向上的Dzyaloshinskii Moriya（DM）相互作用的两分海森贝格XYZ自旋链模型中的局部量子不确定性。在这里，我们表明沿X，Y和Z轴的DM相互作用和自旋相互作用可以增加和维持局部量子渔民信息以及局部量子不确定性。还表明，由于热量量渔民的信息，由于温度的升高，局部量子渔民信息和局部量子不确定性会降低。它们在非常低的温度下等于一个，并且仅在占用温度后才开始腐烂。
In this work we will study the Local quantum Fisher information and the local quantum uncertainty in two-qubit Heisenberg XYZ spin chain model with Dzyaloshinskii Moriya (DM) interaction in z direction. Here we show that the DM interaction and spin interactions along the x, y, and z axis can increase and maintain local quantum Fisher information and local quantum uncertainty. It is also shown that because of thermal fluctuations local quantum Fisher information and local quantum uncertainty are decreased by increasing temperature. They are equal to one at very low temperature and starts to decay only after a thershold temperature.
