This is achieved via phase-shift amplification. The arrangement we propose is based on experimental processes already carried out and does not require the use of any special quantum state.engjournal articlehttp://dx.doi.org/10.1103/PhysRevA.65.025802http://journals.aps.org/open access535Quantum entanglementTrapped ionDecoherenceSuperpositionGenerationAtomCavityMotionÓptica (Física)2209.19 Óptica Física
