Abstract
We study the charge dynamics of a quantum dot as measured by a nearby quantum point contact probing the dot via individual single-particle wave packets. We contrast the two limiting cases of weak and strong system-detector coupling exerting vanishing and strong backaction on the system and analyze the resulting differences in the charge-charge correlator. Extending the study to multiple projective measurements modeling a continuous strong measurement, we identify a transition from a charge dynamics dominated by the system's properties to a universal dynamics governed by the measurement.
