藉由考慮由彼此間有耦合的雙量子點與源極和汲極交互作用所構成的阿哈諾夫-波姆干涉儀，我們研究了鍵合態與反鍵合態以及留過該態的電流的阿哈諾夫-波姆振盪。我們分析了量子態與所對應的電流貢獻之間的關係，而這提供了有用的資訊來透過測量電流重構系統的量子態。我們也驗證了 [Phys. Rev. Lett. 106, 076801 (2011)] 實驗中「不同能量組態的鍵合態電流約略相同」的假定的適用範圍。利用量子點的量子態以及電流的同調性，我們也提供了透過磁通量調控鍵合態與反鍵合態的方法。

By considering a nanoscale Aharonov-Bohm (AB) interferometer consisting of a laterally-coupled double dot coupled to the source and drain electrodes, we investigate the AB phase dependence of the bonding and antibonding states and the transport current via the bonding and antibonding state channels. The relations of the AB phase dependence between the quantum states and the associated transport current components are analyzed, which provides useful information for the reconstruction of quantum states through the measurement of the transport current in such systems. We obtain the validity of the experimental analysis given in [Phys. Rev. Lett. 106, 076801 (2011)] that bonding state currents in different energy configurations are almost the same.
With the coherent properties in the quantum dot states as well as in the transport currents, we also provide a way to manipulate the bonding and antibonding states through the AB magnetic flux.
