Experimental Control with QUDI towards manipulation of single C-13 nuclear spin — •Michel Wolf, Jeremias Resch, Ioannis Karapatzakis, Wolfgang Wernsdorfer, and David Hunger — Karlsruher Institut für Technologie

Quantum networks depend on an interface between photons and long-lived spin degrees of freedom. A promising platform is the tin-vacancy centers in diamond, which offers long electron spin lifetimes due to its strong spin-orbit coupling. To achieve storage times exceeding the communication time between two nodes, even more long-lived nuclear spin degrees need to be coherently addressed. Both the manipulation of these optically addressable spin-qubits and the implementation of quantum network protocols rely on pulse sequences. Therefore, a practical challenge to overcome is the generation of such pulse sequences efficiently as well as the integration to the experimental control orchestrating the required hardware. In this work, we demonstrate the integration of QUDI as a control framework to realize improved and flexible manipulation of a single C-13 nuclear spin.
