      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 ${}^{13}$C nuclear spin strongly coupled to a
                      negatively charged germanium-vacancy center in diamond with
                      coherence times beyond 2.5s 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 18.1s with heating limitations
                      considered, paving the way to successful applications as a
                      quantum repeater node.},
