Abstract

Nuclear spins in semiconductors are promising for quantum technologies. Diamond's nitrogen-vacancy (NV) centers offer long coherence times and an auxiliary electronic qubit. This research demonstrates room-temperature control and photoelectric readout of a single <sup>14</sup>N nuclear spin coupled to an NV electron. The method uses photoelectric detection of magnetic resonance (PDMR), offering nanoscale spatial resolution determined by electrode size, paving the way for scalable electronic quantum processors based on dipolar interactions of closely spaced spin qubits.
