In this work, we introduce a non-Gaussian quantum state named excitedsqueezed vacuum state (ESVS), which can be ustilized to describe quantum lightfield emitted from the multiphoton quantum process occurred in some restrictedquantum systems. We investigate its nonclassical properties such as Wignerdistribution in phase space, photon number distribution, the second-orderautocorrelation and the quadrature fluctuations. By virtue of theHilbert-Schmidt distance method, we quantify the non-Gaussianity of the ESVS.Due to the similar photon statistics, we examine the fidelity between the ESVSand the photon-subtraction squeezed vacuum state (PSSVS), and then find theoptimal fidelity by monitoring the relevant parameters.
