Kicked nonlinear quantum scissors and entanglement generation
A. Kowalewska-Kudłaszyk, W. Leoński, T. Dung Nguyen +1
We consider a nonlinear coupler with two Kerr-like oscillators mutually coupled by continuous linear interaction and excited by a series of ultra-short external pulses. We show tha…

Kullback-Leibler quantum divergence as an indicator of quantum chaos
A. Kowalewska-Kudłaszyk, J. K. Kalaga, W. Leoński +1
We discuss a system of a nonlinear Kerr-like oscillator externally pumped by ultra-short, external, coherent pulses. For such a system, we analyse the application of the Kullback-L…
