We use a quantum pointcontact as a charge detector to perform time-resolved measurements of single-electron tunneling.With increased bias voltage, the quantum point contact exerts a back-action on the interferometerleading to decoherence. We attribute this to emission of radiation from the quantum point contact,which drives non-coherent electronic transitions in the quantum dotsShow less >
