The superposition state from the photon-added two-mode squeezed vacum state a+m|ξ〉 is constructed,and its noclassical properties are numerically studied under the principle of superposition in quantum mechanics.The results reveal that under certain conditions,the mean photon number of the superposition state exhibits oscillating phenomenon of collapses and revivals,bot sub-Poissonian photon statistical character and the phase squeezing of the field in the superposition state are stronger than ones in the single photon-added two-mode squeezed vacuum state.
