Engineering of Quantum Emitter Properties

A single ion coupled to an optical cavity is an efficient source of high-fidelity spin-photon entanglement. We will examine how to engineer this spin-photon entanglement in order to improve the efficiency and fidelity of entanglement between ions at separate nodes of a quantum network. I will present experimental results from a recent quantum-network demonstration on the University of Innsbruck campus and explain how simulations yield insight into these results. Finally, prospects for entangling a trapped ion with a solid-state emitter will be considered.
