摘要：
With variational method of Pekar type and quantum statistics theory, the temperature effects on electron probability density (EPD) of a strongly-coupling electron-LO-phonon (polaron) in RbCl material quantum pseudodots (QPDs) are studied. The qubit in the QPD system can be built by the two-level energy states. The EPD periodically oscillates in the special material QPD with a certain period as the electron is located in the superposition state of the ground and first excited states. The changing functions of EPD and the oscillating period with the system temperature and the chemical potential of the two-dimensional electron gas are found.
