Quantumness and its hierarchies in PT-symmetric down-conversion models
Jan Peřina, Karol Bartkiewicz, Grzegorz Chimczak +4
We investigate the hierarchy of quantum correlations in a quadratic bosonic parity-time-symmetric system (PTSS) featuring distinct dissipation and amplification channels. The hiera…

W-class states-identification and quantification of Bell-CHSH inequalities' violation
Joanna K. Kalaga, Wiesław Leoński, Jan Peřina
We discuss a family of W-class states describing three-qubit systems. For such systems, we analyze the relations between the entanglement measures and the nonlocality parameter for…

Computer simulation of two-mode nonlinear quantum scissors
T. Dung Nguyen, W. Leoński, V. Cao Long
We present a simulation method allowing for modeling of quantum dynamics of nonlinear quantum scissors' (NQS) systems. We concentrate on the two-mode model involving two mutually i…
