Quantum regulation of QMA entropy uncertainty in a qubit-qutrit Heisenberg hybrid spin chain system
The quantum regulation of the entropy uncertainty of quantum memory assisted(QMA)was studied in the qubit-qutrit Heisenberg hybrid spin chain model.The effects of Dzyaloshinskii-Moriya(DM)interaction,coupling strength and inhomogeneous magnetic field on QMA entropy uncertainty in the hybrid spin chain model were analyzed in detail,and the regulatory effects of system parameters on QMA entropy uncertainty and quantum entanglement between the measured system and the memory system in the hybrid spin chain model were compared and analyzed.The results show that by adjusting the inhomogeneous magnetic field strength and the parameters of the hybrid spin chain system,the quantum entanglement between the measured system and the memory system can be improved,This can lead to lower QMA entropy uncertainty and lower bound.
