| 中文摘要 | Overcoming the spin qubit decoherence is a challenge for quantum science and technology. We investigate the decoherence process in nanodiamonds by Carr-Purcell-Meiboom-Gill (CPMG) technique at room temperature. We find that the coherence time T-2 scales as n(gamma). The elongation effect of coherence time can be represented by a constant power of the number of pulses n. Considering the filter function of CPMG decoupling sequence as a function, the spectrum density of noise has been reconstructed directly from the coherence time measurements and a Lorentzian noise power spectrum model agrees well with the experiment. These results are helpful for the application of nanodiamonds to nanoscale magnetic imaging. (C) 2013 Elsevier B.V. All rights reserved, |
