“…The application of spin of electrons in quantum dots for generation of electron entanglement and quantum information processing in solid state devices is of current experimental 1,2,3,4,5,6,7,8,9,10,11 and theoretical interest 12,13,14,15,16,17,18 . Controlling the spin of electrons in single quantum dots by tuning the external magnetic field, the confining potential, number of electrons, and Zeeman coupling has been demonstrated 2,3,4,5,6,7 .…”
