i. thi. contri.uti.n we study a superposi.i.n of two fi.i.e di.ensi.nal tri. coherent states (FTCS). The state i. regarded as a correlated three-mode state i. fi.i.e di.ensi.nal bases. The framework of Pegg and Barnett formalism, and the phase di.tri.uti.n i. addi.i.n to the Poi.soni.n di.tri.uti.n are exami.ed. i. i. shown that the ei.envalue of the di.ference of the photon number (the q-parameter) i. responsi.le for the non-classi.al phenomenon. Furthermore, the quasi.probabi.i.y di.tri.uti.n functi.ns (the Wi.ner and Q-functi.ns) are also di.cussed. i. thi. case and for the Wi.ner functi.n the non-classi.al behavi.r i. only reported for the odd values of the q-parameter.

We study genui.e entanglement among three qubi.s undergoi.g a noi.y process that i.cludes di.si.ati.n, squeezi.g,and decoherence. We obtai. a general soluti.n and analyze the asymptoti. quantum states. We fi.d that most of these asymptoti. states can be genui.ely entangled dependi.g upon the parameters of the channel, memory parameter, and the parameters of the i.i.i.l states. We study Greenberger–Horne–Zei.i.ger(GHZ) states and W states, mi.ed wi.h whi.e noi.e,and determi.e the condi.i.ns for them to be genui.ely entangled at i.fi.i.y. We fi.d that for these mi.tures, i. i. possi.le to start wi.h a bi.separable state(wi.h a speci.i. mi.ture of whi.e noi.e) and end wi.h genui.e entangled states. However, the memory parameter μ must be very hi.h. We fi.d that i. contrast to the two-qubi. case, none of the three-qubi. asymptoti. states for n → ∞ are genui.ely entangled.
