Quantum correlations and entanglement in a model comprised of a short chain of nonlinear oscillators
J. K. Kalaga, A. Kowalewska-Kudłaszyk, W. Leoński +1
We discuss a model comprised of a chain of three Kerr-like nonlinear oscillators pumped by two modes of external coherent field. We show that the system can be treated as nonlinear…
Ground-state entanglement of spin-1 bosons undergoing superexchange interactions in optical superlattices
Artur Barasiński, Wiesław Leoński, Tomasz Sowiński
We discuss a model with ultra-cold atoms confined in optical superlattices. In particular, we study the ground-state properties of two spin-1 bosons trapped in a double-well potent…
A straight waveguide with a wire inducing resonances
Sylwia Kondej, Wiesław Leoński
We study a straight infinite planer waveguide with, so called, leaky wire attached to the walls of the waveguide. The wire is modelled by an attractive delta interaction supported…
Quantum circuits based on qutrits as a tool for solving systems of linear equations
Marek Sawerwain, Wiesław Leoński
Recently, it has been presented some algorithms and physical models which give prospects for construction of quantum computers capable to solve systems of linear equations. The com…
Photon-number entangled states generated in Kerr media with optical parametric pumping
Anna Kowalewska-Kudłaszyk, Wiesław Leoński, Jan Peřina
Two nonlinear Kerr oscillators mutually coupled by parametric pumping are studied as a source of states entangled in photon numbers. Temporal evolution of entanglement quantified b…
