摘　　要：针对由长程相互作用诱导的多端口量子态传输通道,通过在相应的位置引入合适的在位势能,构建了更加鲁棒的多端口量子态传输通道.研究发现在位势能的存在将扩宽体能带与边缘态之间的能隙差,增大绝热演化参数的范围,从而降低了量子态传输所用的时间.For multi⁃port quantum state transmission channels induced by long range interactions,we propose a more robust multi⁃port quantum state transport scheme induced by on⁃site potential added on appropriate site.It is found that the existence of on⁃site potential broadens the gap between the bulk band and the edge states,enlarges the range of adiabatic evolution parameters,and thus reduces the time of quantum state transmission.
