Abstract
Section titled āAbstractāWe propose an efficient method to generate multiparticle entangled states of\nNV centers in a spin mechanical system, where the spins interact through a\ncollective coupling of the Lipkin-Meshkov-Glick (LMG) type. We show that,\nthrough adiabatic transitions in the ground state of the LMG Hamiltonian, the\nGreenberger-Horne-Zeilinger (GHZ)-type or the W-type entangled states of the NV\nspins can be generated with this hybrid system from an initial product state.\nBecause of adiabaticity, this scheme is robust against practical noise and\nexperimental imperfection, and may be useful for quantum information\nprocessing.\n
