Abstract
A spectroscopic approach to measuring a charge qubit placed in a waveguide consisting of three microcavities (a photonic molecule) is discussed. The logical states of a qubit are represented by the single-electron orbitals of a semiconductor double quantum dot. The impact of different factors that cause deviations of the system’s parameters from specified values is investigated. The possibility of controlling the spectrum of a photonic molecule using a local change in its dielectric properties in order to optimize the qubit measurement procedure is analyzed. The functions of the measuring contrast and signal-to-noise ratio are calculated depending on the main parameters of the system.
