  • A symmetric non-equally spaced protocol named adjustable-parameter dynamical decoupling (APDD) was proposed to individually map 13C nuclear spin in diamond. The principles of the APDD sequence are in detail numerically calculated and simulation analyzed. The 13C nuclear spin addressing accuracy of APDD protocol was compared with Carr-Purcell-Meiboom-Gill (CPMG) and XY4 protocol, which are most widely used in diamond atom quantum manipulation. Results show that the 13C nuclear spin addressing accuracy of APDD protocol was 6.27 times higher than CPMG and XY4 sequences. Furthermore, τ1/τ ratio ranging from 0.51 to 0.58 is the best operating condition for APDD protocol. The APDD protocol will pave the way towards manipulation of the nuclear spins surrounding the NV-color center in diamond, which has significant applications in quantum information and quantum detector.
