Sum squeezing

In this paper, we study some non-classical properties and propose the generation schemes of the superposition of multiple-photon-added two-mode squeezed vacuum state (SMPA-TMSVS). Based on the Wigner function, we clarify that this state is a non-Gaussian state, while the original twomode squeezed vacuum state (TMSVS) is a Gaussian state.

In this paper, we study some higher-order nonclassical properties of the superposition of three-mode photon-added trio coherent states such as antibunching, squeezing, and entanglement. The results show that, for a fixed order, when the number of added photons is increased, the three-mode sum squeezing is more obvious, but the degrees of antibunching and three-mode entanglement are less manifested.

This paper studies the higher-order nonclassical and entanglement properties in the photonadded trio coherent state (PATCS). We use the criterion of higher-order single-mode antibunching to evaluate the role of the photon addition operation. Furthermore, the general criteria for detection of higher-order three-mode sum squeezing and entanglement features in the PATCS are also investigated.

We study the nonclassical properties of single-photon-added two-mode SU(1,1) coherent states. We derive the analytic expressions of the sum squeezing, the difference squeezing, the higher-order squeezing, the higher-order antibunching and the violation of the Cauchy– Schwarz inequality.
