Electric and temperature control of parameters of a charge qubit in a microresonator under technological deviations
A V Tsukanov, I Yu Kateev
Abstract
Abstract Effect of statistical deviations of geometric sizes on operating parameters of an optically controlled semiconductor quantum dot (QD) charge qubit is studied. A numerical analysis of averaged spectra of a double QD and a photonic crystal microresonator (MR) is carried out in the presence of technological imperfections of their parameters. An estimate for correction electric field amplitudes that compensate for deviations of the real qubit parameters from the calculated ones is obtained. The possibility of correcting the optical spectrum of the MR by changing its temperature is shown.
