Abstract
We investigate a candidate for the potential implementation of entanglement purification of two entangled nitrogen vacancy (N-V) centers that are coupled with two microtoroidal resonators. In our proposed entanglement purification protocol (EPP), mixed entangled ensembles can be purified with the local parity-check operations. With current and near-future technology, we can achieve the maximally entangled N-V centers nonlocally. And our EPP can be used in quantum repeaters for long-distance quantum communication.
