Abstrakt: This study investigates the local quantum uncertainty (ℒ ) 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 with the coupling coefficient J may produce a more efficient operation to enhance the correlation. [ABSTRACT FROM AUTHOR]
