Non-Markovianity of a double-dot qubit in a suspended phonon cavity

Abstract

In this thesis we investigate non-Markovianity of a double-dot qubit in a suspended phonon cavity Pure dephasing due to the electron-phonon interaction plays an important role in the system It leads information lose from qubit to the environment By changing distance between dots and thickness of slab the non-Markovianity varies We also find the non-Markovianity can be strongly related to the dephasing factor
