Influence of configuration and acoustic phonons on three-qubit controlled-phase gate

Abstract

We discuss the configuration and acoustic phonon effect on the conditional phase gate using self assembled quantum dots. As an example, we discuss the simplest three dots conditional phase gate, and we found that the fidelity of conditional phase gate depends strongly on the configuration and temperature. Numerical simulation shows that line-configuration resonant with lower single exciton energy level performs better during the gate operation.
