Abstract
Section titled āAbstractāThe coupled negatively charged nitrogen-vacancy (NVā) center system is a promising candidate for scalable quantum information techniques. In this work, ionized nitrogen molecules are implanted into bulk diamond to generate coupled NVā center pairs. The two-photon autocorrelation measurement and optically detected magnetic resonance measurement are carried out to confirm the production of the NVā center pair. Also, both 1.3 Ī¼s decoherence time and 4.9 kHz magnetic coupling strength of the NVā center pair are measured by controlling and detecting the spin states. Along with nanoscale manipulation and detection methods, such coupled NVā centers through short distance dipole-dipole interaction would show high potential in scalable quantum information processes.
