Abstract In this paper we construct real and imaginary cat states of graphene and examine some properties of such states. It has been shown that these cat states exhibit nonclassical features like oscillation of the distribution function, sub-Poissonian statistics and quadrature squeezing.

The real and imaginary negative binomial states formed by a superposition of the negative binomial states are introduced. The sub-Poissonian statistics, Wigner function and squeezing properties of the real and imaginary states are studied in detail. The oscillatory character of the photon distribution due to the quantum interference between the two components is shown. Moreover, we find that these states are real and imaginary nonlinear Schrödinger cat states and give the corresponding ladder operator formalisms. We also discuss how to generate these general real quantum superposition states based on the intensity-dependent Jaynes-Cummings model.
