    "abstract": "We propose a potential scheme to generate entangled photons by manipulating\ntrapped ions embedded in two-mode microcavities, respectively, assisted by a\nmagnetic field gradient. By means of the spin-spin coupling due to the magnetic\nfield gradient and the Coulomb repulsion between the ions, we show how to\nefficiently generate entangled photons by detecting the internal states of the\ntrapped ions. We emphasize that our scheme is advantageous to create complete\nsets of entangled multi-photon states. The requirement and the experimental\nfeasibility of our proposal are discussed in detail.",
