• We have investigated the quantum Zakharov equations and the existence of quantum solitons in the fully nonlinear quantum wave. For simplicity, we use the so-called sech and tanh expansion method, and obtain several new quantum solitary wave solutions, such as the bright soliton, gray soliton, W-soliton and M-soliton. In contrast to the classical Zakharov equations, in the case of quantum Zakharov equations, the terms proportional to H^2 modified the dispersion-nonlinearity equilibrium, which is the ultimate responsible for the existence of solitons. Furthermore, changing H may affect the nature of the solutions in a fundamental way. In addition, some properties of the quantum solitons that we obtained in the fully nonlinear quantum waves are different from those in the weakly nonlinear limit [F. Haas et al. : Phys. Plasmas 10 (2003) 3858].
