## Abstract Review of the probability representation of quantum states based on the tomographic‐probability notion is presented. Classical and quantum states are studied and the difference of tomographic probabilities describing the states in both domains is elucidated. New expressions for fidelity
We introduce photon-added and photon-subtracted two-mode squeezed vacuum states and examine the quantum statistical properties of these states by analytic calculating. Because of the entanglement between the modes of the field in a Ž . two-mode squeezed state, photon adding or subtracting for one of
