In this paper, we study some quantum properties of a superposition of displaced squeezed two-mode vacuum and single-photon states, such as the second-order correlation function, the Cauchy-Schwarz inequality, quadrature squeezing, quasiprobability distribution functions and purity. A generation scheme for such states is given.
Jsou určeny kvantové vlastnosti superpozice stavů z hlediska korelační funkce druhého řádu, Cauchyho-Schwarzovy nerovnosti kvadraturního stlačení, rozdělení kvazipravděpodobností a čistoty. Je uvedeno schema pro generaci stavů.
