We demonstrate the super-resolution localization of the nitrogen vacancy\ncenters in diamond by a novel fluorescence photoswitching technique based on\ncoherent quantum control. The photoswitching is realized by the quantum phase\nencoding based on pulsed magnetic field gradient. Then we perform\nsuper-resolution imaging and achieve a localizing accuracy better than 1.4 nm\nunder a scanning confocal microscope. Finally, we show that the quantum phase\nencoding plays a dominant role on the resolution, and a resolution of 0.15 nm\nis achievable under our current experimental condition. This method can be\napplied in subnanometer scale addressing and control of qubits based on\nmultiple coupled defect spins.\n
