本文研究了 three-qubit海森堡XYZ各向异性自旋链系统各项参数和外加磁场对量子存储支撑(Quantum memory assisted,QMA)熵不确定度及其下限的调控行为,以及对被测系统与存储系统之间量子纠缠的影响.结果表明:增大系统的Dzyaloshinski-Moriya(DM)相互作用强度、降低系统温度、增大沿Z正方向磁场强度可以提高被测系统与存储系统之间的量子纠缠,降低系统QMA熵不确定度及其下限,被测系统与存储系统之间的量子纠缠与QMA熵不确定度及其下限呈类反相关.
Quantum regulation of QMA entropy uncertainty in three-qubit Heisenberg XYZ anisotropic spin chain system
In this paper,the regulation behavior of various parameters and applied magnetic field of the three-qubit Heisenberg XYZ anisotropic spin chain system on Quantum memory assisted(QMA)entropy uncertainty and its lower bound,and the influence on the quantum entanglement between the measured system and the memory system are studied.The results show that increasing the Dzyaloshinski-Moriya(DM)interaction strength,reduc-ing the system temperature,and increasing the magnetic field strength in the positive Z direction can improve the entanglement between the measured system and the memory system,and reduce QMA entropy uncertainty and its lower bound,the quantum entanglement between measured system and the memory system is inversely correlated with the QMA entropy uncertainty and its lower bound.
