We present a potential scheme to entangle negatively charged nitrogen-vacancy (N-V) centers in distance using nanomechanical resonators (NAMRs) and a common superconducting quantum interference device (SQUID). By virtually exciting the vibrational modes of the NAMRs, we show the effective coupling between the N-V centers and the SQUID, which is a promising step toward large-sized quantum-information processing with separate N-V centers. ©2010 The American Physical Society
