Time-resolved detection of single-electron interference
Résumé
We demonstrate real-time detection of self-interfering electrons in a double quantum dot embedded
in an Aharonov-Bohm interferometer, with visibility approaching unity. We use a quantum point
contact 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 interferometer
leading to decoherence. We attribute this to emission of radiation from the quantum point contact,
which drives non-coherent electronic transitions in the quantum dots
