The relation between three types of three-mode squeezing operators and the tripartite entangled state
Hong-Yi Fan, Nian-Quan Jiang · Journal of Optics B Quantum and Semiclassical Optics · 2004
Based on the newly constructed tripartite entangled state of continuum variables (Fan and Jiang 2003 J. Opt. B: Quantum Semiclass. Opt. 5 283) we introduce three different, but mutually commutable, squeezing operators which can squeeze any three-mode quantum states; in particular they squeeze to , and respectively. Schemes of implementing these squeezing operators are briefly discussed.
