Abstract (summary) In this paper we study the backaction of measuring tunneling current through double quantum dot on it’s dynamics. We propose a new method for evaluating of measured current operator. Results are demonstrated as a graph representing measured stationary current through double quantum dot as a function of detection performance. It is shown that increasing of detection performance leads to quick decreasing of current through double quantum dot, which is consistent with quantum Zeno effect.
