We present a device model of the polariton logic element that is able to work both with classical and quantum signals. This device uses the nonlinear and quantum properties of exciton-polaritons. The mathematical description of our model is based on stochastic quantum equations with a complex diffusion in the Ito formalism with the corresponding quasi-probability in the quantum phase space. It is shown that the stationary states in the bistable mode can be controlled by both classical and quantum signals through the stochastic resonance within the region of quantum phase transition. Based on these properties, the model of the quantum logic elements has been developed.
