Optimal absorption of a photon by a quantum node — Susanne Blum^1,2, •Tom Schmit¹, Daniel Reich^3,4, Tommaso Calarco⁵, Christiane Koch³, and Giovanna Morigi¹ — ¹Universität des Saarlandes, Saarbrücken, Germany — ²Theodor-Heuss-Gymnasium, Esslingen, Germany — ³Universität Kassel, Kassel, Germany — ⁴Universität Aarhus, Aarhus, Denmark — ⁵Universität Ulm, Ulm, Germany

We discuss protocols for achieving perfect absorption of a photon by a single trapped atom, or solid-state emitter, in a high-finesse cavity. Specifically, we compare the efficiency of protocols based on adiabatic transfer with the one of protocols based on optimal control theory. We focus on the setup of [Reiser et al., Nature 508, 237 (2014)]. Our ultimate goal is to identify the conditions on external fields driving the atom, which are required for absorbing a photon of arbitrary spectral form. We discuss the efficiency of the protocols for a certain class of photonic wave forms. This analysis contributes to the development of a toolbox for quantum networks using hybrid platforms.
