  Population evolution in a magnetic impurity doped semiconductor quantum dot
has been studied by applying a sequence of pulses of chosen pulse area. By
optical excitation mechanism, the population in (J_z=+3/2), heavy hole state of
valence band is carried over to (J_z=-3/2), valance band state, via the
(J=+1/2) conduction band states. The injected microwaves entangle conduction
band states. This arrangement is successfully employed to ascertain quantum
CNOT operation, and the calculation predicts maximum fidelity of 80\% for the
CNOT operation.
