Exploring entanglement, Wigner negativity and Bell nonlocality for anisotropic two-qutrit states
Huan Liu, Zu-wu Chen, Xue-feng Zhan +2
We introduce a family of anisotropic two-qutrit states (AITTSs). These AITTSs are expressed as $ρ_{aiso}=p\left\vert ψ_{\left( θ,ϕ\right) }\right\rangle \left\langle ψ_{\left( θ,ϕ\…

Noiselessly amplified thermal states and after multi-photon addition or subtraction
Xue-feng Zhan, Xue-xiang Xu
In this paper, we introduce a noiselessly amplified thermal state (ATS), by operating the noiseless amplification operator () on the thermal state (TS) with correspond…
