Abstract

We present an analysis of waiting time distributions of consecutive single-electron transfers through a double-quantum-dot Aharonov-Bohm interferometer. Waiting time distributions qualitatively indicate the presence of interferences and provide information on orbital-detuning and coherent interdot-electron transfer. The frequencies of interdot-transfer–induced oscillations are Aharonov-Bohm phase sensitive, while those due to level detuning are phase independent. The signature of the quantum interference in the waiting-time distribution is more apparent for weakly coupled electron transfer detectors.
