Coherent control of localization, entanglement, and state superpositions in a double quantum dot with two electrons

We have recently proposed a quantum control method based on the knowledge of the energy spectrum as a function of an external control parameter. So far, our method has been applied to connect the ground state to target states that were in all cases energy eigenstates. In this paper we extend that me...
