Show affiliationsWe report on correlated real-time detection of individual electrons in an InAs nanowire double quantum dot (DQD). Two self-aligned quantum point contacts (QPCs) in an underlying two-dimensional electron gas material serve as highly sensitive charge detectors for the DQD. Tunnel processes of individual electrons and all tunnel rates are determined by simultaneous measurements of the correlated signals of the QPCs.
