| Abstract
|
| 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, reducing 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. |
