Physical Review Letters, 122(1).0031-9007https://hdl.handle.net/10016/32123We develop energy efficient, continuous microwave schemes to couple electron and nuclear spins, using phase or amplitude modulation to bridge their frequency difference. These controls have promising applications in biological systems, where microwave power should be limited, as well as in situations with high Larmor frequencies due to large magnetic fields and nuclear magnetic moments. These include nanoscale NMR where high magnetic fields achieves enhanced thermal nuclear polarization and larger chemical shifts. Our controls are also suitable for quantum information processors and nuclear polarization schemes.6eng© 2019 American Physical SocietyQuantum controlQuantum sensingNitrogen vacancy centers in diamondAtomic, molecular & opticalresearch articleFísicahttps://doi.org/10.1103/PhysRevLett.122.010407open access010407-11010407-6Physical Review Letters122AR/0000026549
