Research output: Contribution to journalArticlepeer-review


A controlled dephasing in an interfering mesoscopic system was realized by creating an entangled system between a DQD interferometer and a phase sensitive QPC detector. The dephasing process was understood both from the 'which path' information provided by the detector and from the effect of charge fluctuations in the detector on the interferometer.
