Control Protocols for Entangling Gates for Group-IV Color-Centers in Diamond
Jurek Frey, Frank K. Wilhelm, Matthias M. Müller
Accurately controlling entangling gates remains a major challenge for quantum technology applications with solid-state spin qubits. Here, we study a group-IV color-center with a st…

Coherent Control of a Long-Lived Nuclear Memory Spin in a Germanium-Vacancy Multi-Qubit Node
Nick Grimm, Katharina Senkalla, Philipp J. Vetter +6
The ability to process and store information on surrounding nuclear spins is a major requirement for group-IV color center-based repeater nodes. We demonstrate coherent control of…
