Quantum information technologies require stable, scalable and efficiently controllable qubits. Quantum dot molecules (QDMs) can host qubits that meet these requirements. To realize these qubits, it is necessary to simultaneously control the charge state, orbital coupling and charge spin in a QDM.
In this work, we demonstrate the simultaneous control of charge state and orbital coupling via tunnel ionization. The generated state is coherently controlled and the spin is initialized and measured. This paves the way for the deterministic generation of 2D cluster states.
