ABSTRACT

In this work we extend our previous studies on the quantum transfer of a particle through a finite-bandwidth continuum under frequent detections by replacing the assumed frequent measurements with a genuine continuous monitoring with a point-contact detector. We present a quantitative comparison between the two types of measurement. We also propose possible measurements, based on state-of-the-art experiments, to test the “scaling” property between the measurement rate and the bandwidth of the reservoir, rooted in the transfer dynamics under continuous monitoring.
