Coupling of quantum systems to an engineered reservoir provides new opportunities for quantum state generation and open-systems quantum engineering. We have recently demonstrated a new form of reservoir engineering following the proposal of [1], allowing us to generate superposition states of trapped-ion motion as the dark state of the engineered dissipation process. I will describe this work, and in addition quantum control of calcium ion optical-qubits in our micro-structured segmented linear Paul trap.
