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.

摘要

讨论了一种测量放置在由三个微腔(光子分子)组成的波导中的电荷量子位的光谱方法。量子位的逻辑状态由半导体双量子点的单电子轨道表示。研究了导致系统参数偏离指定值的不同因素的影响。分析了使用其介电特性的局部变化来控制光子分子光谱以优化量子位测量程序的可能性。测量对比度和信噪比的功能取决于系统的主要参数。
