    摘要: We investigate the dependence of decoherence on the mode number M in a multiple-mode Aharonov-
    Bohm (AB) interferometer. The design of the AB interferometer allows us to precisely determine M by the
    additivity rule of ballistic conductors; meanwhile, the decoherence rate is simultaneously deduced by the
    variance of the AB oscillation amplitude. The AB amplitude decreases and fluctuates with depopulating
    M. Moreover, the normalized amplitude exhibits a maximum at a specific M (∼9). Data analysis reveals
    that the charge-fluctuation-induced dephasing, which depends on the geometry and the charge relaxation
    resistance of the system, could play an essential role in the decoherence process. Our results suggest that the
    phase coherence, in principle, can be optimized using a deliberated design and pave one of the ways toward
    the engineering of quantum coherence.
