考虑电子与表面光学声子相互作用的极性晶体膜量子比特
Polar crystal film quantum bit considering interaction between electrons and SO phonons
摘要
Abstract
Based on linear combination operator and variational method,the qubits and its phonon effects of electron phonon interaction system,in which the coupling of electron and surface optical (SO) phonon is strong,the coupling of electron and bulk longitudinal optical phonon is weak,are discussed in polar crystal film.When the electron is in the superposition state of the ground state and first excited state,the probability density of electrons is periodically oscillating in space.Results show that the oscillation period decreases with the increasing of coupling strength,and increases with the increasing of polaron vibration frequency.Considering the interaction between electron and SO phonon,the polaron vibration frequency changes,which causes the change of probability density of the electron.关键词
