通过实验和数值模拟研究了开放量子点阵列中电子干涉的细节。可再现的波动中观察到的低温磁导和这些特性的建议是一致的过渡从多个到单点的干扰，发生的interdot耦合的强度是不同的。因此，这些结果揭示了量子点阵列中的电导波动的非平凡缩放，这被认为是由于能量杂化上的点间耦合的影响而产生的。
The details of electron interference in open quantum-dot arrays are studied in experiment and numerical simulations. Reproducible fluctuations are observed in their low-temperature magnetoconductance and the characteristics of these are suggested to be consistent with a transition from multiple to single-dot interference, which occurs as the strength of the interdot coupling is varied. These results therefore reveal a nontrivial scaling of the conductance fluctuations in quantum-dot arrays, which is thought to arise due to the influence of the interdot coupling on energy hybridization.
