Abstract

Injecting a Fock state and an ancillary squeezed vacuum state into a beam-splitter (BS) device and then employing continuous-variable postselection detection in one output port, a postselected quantum state is generated in another output port. We derive the detailed analytical expressions of the density operator for the output state. Then we study the success probability analytically and numerically. In what follows, we study some properties for the generated state, including photon-number representation, Mandel Q parameter and Wigner function. Expressions for every property are given and numerical analyses are employed by changing different interaction parameters. The results show the nonclassical properties will be displayed in proper interaction parameters.
