Entangled coherent states and squeezing in N trapped ions
E Solano, R L de Matos Filho, N Zagury · Journal of Optics B Quantum and Semiclassical Optics · 2002
We consider a resonant bichromatic excitation of N trapped ions that generates displacement and squeezing in their collective motion conditioned to their ionic internal state, producing eventually Schrödinger cat states and entangled squeezing. Furthermore, we study the case of tetrachromatic illumination for producing the so-called entangled coherent states in two motional normal modes.
