We present a statistical readout method for quantum interferences based on time series analysis 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. 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.
