Fisher information and multiparticle entanglement
Philipp Hyllus, Wiesław Laskowski, Roland Krischek +5
The Fisher information gives a limit to the ultimate precision achievable in a phase estimation protocol. It has been shown recently that the Fisher information for a linear tw…
Permutationally invariant quantum tomography
Geza Toth, Witlef Wieczorek, David Gross +3
We present a scalable method for the tomography of large multiqubit quantum registers. It acquires information about the permutationally invariant part of the density operator, whi…
Non-classicality thresholds for multiqubit states - numerical analysis
Jacek Gruca, Wieslaw Laskowski, Marek Zukowski +4
States that strongly violate Bell's inequalities are required in many quantum informational protocols as, for example, in cryptography, secret sharing and the reduction of communic…
