We plan to investigate non-Markovian spin-bath dynamics of single nitrogen-vacancy (NV) centers in type-Ib and type-IIa diamond [1]. We show that a simple phenomenological model known as the post-Markovian master equation (PMME) can be used to capture a non-Markovian component of the spin-bath dynamics. We utilize PMME and quantum state tomography measurements to probe non-Markovian spin dynamics of the single NV center. Moreover, the trace-norm distance between two different initial states will be used to quantify the degree of non-Markovianity observed in the NV spin dynamics.
