The benefit of quantum point contact (QPC) to enhance the detector sensitivity to the single-electron charging in a quantum dot was described. The QPC is based on the self-consistent solution of coupled three-dimensional Kohn-Sham and Poisson equations for the quantum circuit. The single-quantum measurement achieved in quantum circuit helps in realization of electronic devices for quantum information processing. The computer modeling was used to simulate the correlation between the charging of the quantum states in the laterally coupled quantum dot (LCQD) and the electrostatic varaition in the QPC.
