中文摘要	in this paper we consider the continuous weak measurement of a solid-state qubit by single electron transistors (set). for single-dot set, we find that in nonlinear response regime the signal-to-noise ratio can violate the universal upper bound imposed quantum mechanically on any linear response detectors. we understand the violation by means of the cross-correlation of the detector currents. for double-dot set, we discuss its robustness against wider range of temperatures, quantum efficiency, and the relevant open issues unresolved.
