  Current typical methods to realize nuclear-nuclear quantum gates require a
sequence of electronnuclear quantum gates by using dynamical decoupling
techniques, which are implemented at low temperature because of short
decoherence and relaxation time of the NV spin at room temperature. This
limitation could be overcome by using periodical resets of an NV spin as a
mediator of interaction between two nuclear spins [Chen, Schwarz, and Plenio,
119, 010801 (2017)]. However, this method works under stringent coupling
strengths condition, which makes it not applicable to heteronuclear quantum
gate operations. Here we develop this scheme by using radio-frequency (RF)
fields to control different nuclear spin species. Periodical resets of the NV
center protect the nuclear spins from decoherence and relaxation of the NV
spin. RF control provides probability to have highly selective and high
fidelity quantum gates between heteronuclear spins as well as detecting nuclear
spins by using a nuclear spin sensor under ambient conditions.
