Polar Slab Qubit and its Optical Phonon Effect in Finite Well
Xiao Jing-lin · Acta Sinica Quantum Optica · 2012
By using variational method of Peakar type,studied the polar slab qubit and its optical phonon effect in finite well,This system in a polar slab can be employed as a system-qubit.When the electron is in the superposition state of the ground state and the first excited state,we obtained the time evolution of the electron density.It is shown that the period of oscillation decreases with the strength of coupling increasing,but increases with the slab thickness.
