Abstract

We demonstrate that the multiparticle Hanbury Brown–Twiss interferometer can be realized in a network of nitrogen-vacancy centers: for an $N$ -particle system, the interference effect is manifested only in the $N$ th-order intensity correlation function. The interference effect can be enhanced through a postselection process in which the multipartite Greenberger-Horne-Zeilinger entanglement is generated and tested with Svetlichny inequality.
