| Summary: | 碩士 === 國立成功大學 === 物理學系 === 103 === 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.
