Effect of optical phonons on the charge qubit dynamics in a semiconductor microcavity

Abstract: We consider the possibility of using optical vibrational degrees of freedom as an additional resource for controlling the evolution of a charge qubit based on a semiconductor single-electron double quantum dot. The effect of electron – photon – phonon processes on the accuracy of single-qubit operations is investigated. It is shown that, depending on the phonon decay rate and detuning of the electronic transition frequency from the optical phonon frequency, these processes can both facilitate and prevent coherent electron transfer between quantum dots.

Keywords: quantum computer, qubit, quantum dot, microcavity, optical phonons.
