| contents | We theoretically investigate long-range coherent charge transport in linear quadruple quantum dot (QQD) arrays under reduced symmetry configurations. Employing a master equation approach, we identify precise resonant conditions that enable minimal occupation of intermediate dots, thereby facilitating long-range transfer between distant sites. Our results highlight the critical role of parameter asymmetry and coherent tunneling mechanisms in achieving efficient quantum state transfer. |
