Abstract

This study investigates the local quantum uncertainty (LQU) of a two--qubit Heisenberg XY chain with different directions of Dzyaloshinskii--Moriya (DM) interactions. The DM interaction parameters and coupling coefficient $J$ are demonstrated to be beneficial in managing correlation. The DM interaction's x--axis parameter has more influence on correlation than the DM interaction's z--axis. As a result, adjusting the direction of the DM interaction may be capable of producing a more efficient operation to improve the correlation.
