Abstract We show how the two interacting electrons in a field-driven coupled quantun dot can be used to prepare maximally entangled Bell states. The time durations of oscillatory electric field for producing and maintaining such highly entangled states are identified by both analytic and exact numerical solution of the quantum dynamical equations.
