Given a large degree of tuning of the electrostatic potential
landscape with seven electrodes we search for well configurations
corresponding to three different types of interaction between two
electrons.
- In configuration I we address both qubits independently and can thereby perform single-qubit state rotations.
- Configurations II and III correspond to avoided level crossings between two (\( E_{01}, E_{10} \)) and three (\( E_{11}, E_{20}, E_{02} \)) energy levels respectively, where the electrons' motion becomes correlated, that is they are entangled.
