摘要：
We explore into the non-classical characteristics of a new entangled coherent state (CS), also known as a multi-photon addition amplified coherent state (MPAACS) gn̂â†m, which is produced by adding any quantity of photons to two-mode coherent states with various gain factor values. A superposition of photon-added amplified two-mode CSs (MPAACS) also exists in this novel entangled state. It is proven that the gain factor and Laguerre polynomials are related to the MPAACS normalization factor. Analytical discussion is also had regarding entanglement and quantum statistical properties. Regarding concurrence, our findings further suggest that by selecting suitable values for the gain factor g, photon added (m,n), and coherent amplitude, entanglement for the output state can occur. Specifically, the enhancement of the entanglement can be found at large g values at fixed (m,n) in comparison to (m,n) values at fixed g and small amplitude with ϕ=0 or pi. Besides that, the analyses of nonclassicality reveal that, when comparing the results for several values (m,n) at fixed g and with several values g at fixed (m,n), the low-order antibunching effect, the cross-correlation function, and the Wigner function all support the sub-Poissonian statistics. When analyses of the nonclassicality and the negative value of the WF for ϕ=0 are larger at fixed parameter (m,n), but larger at g fixed for ϕ=π, the TMAA-TMC states perform better. © 2024 Elsevier GmbH
