We provide a family of non-Gaussian pure entangled states ina bipartite system as the eigenstates of a quadratic Hamiltoniancomposed of Einstein–Podolsky–Rosen-like operators. The ground state of the Hamiltoniancorresponds to the two-mode-squeezed vacuum and belongs to the Gaussianstates. In contrast, all of the excited states are non-Gaussianstates. A separable inequality maximally violated by the eigenstates isderived. ©2010
