Simultaneous estimation of multiple phases in generalised Mach-Zehnder interferometer
Marcin Markiewicz, Mahasweta Pandit, Wieslaw Laskowski
In this work we investigate the problem of simultaneous estimation of phases using generalised three- and four-mode Mach-Zehnder interferometer. In our setup, we assume that the ph…
Experimentally friendly approach towards nonlocal correlations in multisetting N -partite Bell scenarios
Artur Barasiński, Antonín Černoch, Wiesław Laskowski +3
In this work, we study a recently proposed operational measure of nonlocality by Fonseca and Parisio~[Phys. Rev. A 92, 030101(R) (2015)] which describes the probability of violatio…
Gaussian state entanglement witnessing through lossy compression
Waldemar Klobus, Pawel Cieslinski, Lukas Knips +2
We propose a method to witness entanglement between two continuous-variable systems in a Gaussian state. Its key ingredient is a local lossy state transfer from the original spatia…
Cooperation and dependencies in multipartite systems
Waldemar Klobus, Marek Miller, Mahasweta Pandit +7
We propose an information-theoretic quantifier for the advantage gained from cooperation that captures the degree of dependency between subsystems of a global system. The quantifie…
