(a) Coherence vs evolution time with only nuclear spin noise, the variance of the random magnetic field is set to be \(0.2\) Gauss. (b) Coherence time vs λ extracted from (a). (c)Evolution of population with time in real NV center, in which both nuclear spin noise and electron noise are considered, the dots are simulated points and the curves are fitted one. (d) Coherence time got from the fitting curve in (c) vs λ from 0 to 3, here the values of λ in the calculation are 0, 0.25, 0.5, 0.75, 1, 2, 3.
