“…This type of squeezing arises in a natural way in second-harmonic generation and in a number of nonlinear optical processes. After that the ASS and more higher-order squeezing of radiation fields have been investigated in various physical systems [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48], and these theoretical studies have suggested a possibility to extract information from an optical signal by higher-order correlation measurements. This has attracted our interest as a means of exploring states which possess higher-order squeezing.…”

We know that the original Schrödinger cat states has no amplitude-squared squeezing. In this paper, we investigate the amplitude-squared squeezing of Schrödinger cat states using postselected von Neumann measurement. The results show that after postselected von Neumann measurement, the amplitude-squared squeezing of Schrödinger cat states change dramatically and this can be considered a result of weak value amplification. The squeezing effect also investigated by studying the Wigner function of Schrödinger cat states after postselected measurement.

In this paper, ordinary and amplitude-squared squeezing as well as Wigner functions of singlephoton-added coherent state after postselected von Neumann measurements are investigated. The analytical results show that the von Neumann type measurement which is characterized by postselection and weak value can significantly change the squeezing feature of single-photon-added coherent state. It is also found that the postselected measurement can increase the nonclassicality of the original state in strong measurement regimes. It is anticipated that this work could may provide an alternate and effective methods to solve state optimization problems based on the postselected von Neumann measurement technique.
