    "abstract": "We consider a resonant bichromatic excitation of N trapped ions that\ngenerates displacement and squeezing in their collective motion conditioned to\ntheir ionic internal state, producing eventually Scrhodinger cat states and\nentangled squeezing. Furthermore, we study the case of tetrachromatic\nillumination or producing the so called entangled coherent states in two\nmotional normal modes.",
