Nuclear spin state control of a single atom's magnetic core using RF voltage pulses via scanning tunneling microscope tip

Summary: Overcomes fundamental decoherence limits in single-atom qubits by manipulating nuclear magnetic resonances directly, achieving ultra-long quantum coherence times without disturbing surrounding electronic shells. This atomic-scale nuclear spin control mechanism provides a physical foundation for constructing fault-tolerant single-atom quantum memory registers and atomic-scale spintronic processing units.
