Abstract
In this paper, the quantum statistical properties of a class of superposed q-deformed generalized coherent states a vertical bar beta > + be(i Phi) vertical bar beta e(i delta)> are studied. The results show that the superposition of q-deformed coherent generalized states generally exhibits squeezing and anti-bunching effects. The change of the phase difference between two generalized coherent states, the phase difference between two superposition coefficients, and both the amplitude and phase of the inner product of two generalized coherent states play important roles in squeezing effect and anti-bunching effect.
