Decoherence and dynamical decoupling control of nitrogen vacancy center electron spins in nuclear spin baths
Decoherence and dynamical decoupling control of nitrogen vacancy center electron spins in nuclear spin baths
We theoretically study the decoherence and the dynamical decoupling control of nitrogen vacancy center electron spins in high-purity diamond, where the hyperfine interaction with ${}^{13}$C nuclear spins is the dominating decoherence mechanism. The decoherence is formulated as the entanglement between the electron spin and the nuclear spins, which is induced …
