Multipartite entanglement
Pawel Horodecki, Łukasz Rudnicki, Karol Życzkowski
In this contribution we present a concise introduction to quantum entanglement in multipartite systems. After a brief comparison between bipartite systems and the simplest non-triv…
Suppression of noise in separation estimation of optical sources with spatial-mode demultiplexing
Fattah Sakuldee, Łukasz Rudnicki
Spatial mode demultiplexing was proved to be a successful tool for estimation of the separation between incoherent sources, allowing for sensitivity much below the Rayleigh limit.…
Classicality of the Bogoliubov transformations and the dynamical Casimir effect through the reduced state of the field
Tomasz Linowski, Łukasz Rudnicki
We use the reduced state of the field formalism [Entropy 21, 705 (2019)] to derive conditions under which a Bogoliubov transformation can be considered semi-classical. We apply thi…
Salient signatures of entanglement in the surrounding environment
Łukasz Rudnicki, Waldemar Kłobus, Otavio A. D. Molitor +1
We develop a model in which presence of entanglement in a quantum system can be confirmed through coarse observations of the environment surrounding the system. This counter-intuit…
Geophysics and Stuart vortices on a sphere meet differential geometry
Łukasz Rudnicki
We prove new existence criteria relevant for the non-linear elliptic PDE of the form , considered on a two dimensional sphere , in the parameter regime $2\…
Quantum speed limit helps interpret geometric measure of entanglement
Łukasz Rudnicki
Using the approach offered by quantum speed limit, we show that geometric measure of multipartite entanglement for pure states [Phys. Rev. A 68, 042307(2003)] can be interpreted as…
