Abstract
Section titled āAbstractāThe coherent high-fidelity generation of nuclear spins in long-lived singlet\nstates which may find application as quantum memory or sensor represents a\nconsiderable experimental challenge. Here we propose a dissipative scheme that\nachieves the preparation of pairs of nuclear spins in long-lived singlet states\nby a protocol that combines the interaction between the nuclei and a\nperiodically reset electron spin of an NV center with local rf-control of the\nnuclear spins. The final state of this protocol is independent of the initial\npreparation of the nuclei, is robust to external field fluctuations and can be\noperated at room temperature. We show that a high fidelity singlet pair of a\n13C dimer in a nuclear bath in diamond can be generated under realistic\nexperimental conditions.\n
