      abstract     = {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 a 13C nuclear spin strongly coupled to a negatively
                      charged germanium-vacancy center in diamond with coherence
                      times beyond 2.5 s at mK temperatures, which is the longest
                      reported for group-IV defects. Detailed analysis allows us
                      to model the system’s dynamics, extract the coupling
                      parameters, and characterize noise. We estimate an
                      achievable memory time of 18.1 s with heating limitations
                      considered, paving the way to successful applications as a
                      quantum repeater node.},
