Scalable Bell inequalities for qubit graph states and robust self-testing
F. Baccari, R. Augusiak, I. Šupić +2
Bell inequalities constitute a key tool in quantum information theory: they not only allow one to reveal nonlocality in composite quantum systems, but, more importantly, they can b…
Separability gap and large deviation entanglement criterion
Jakub Czartowski, Konrad Szymański, Bartłomiej Gardas +2
For a given Hamiltonian on a multipartite quantum system, one is interested in finding the energy of its ground state. In the separability approximation, arising as a nat…
Distinguishing classically indistinguishable states and channels
Kamil Korzekwa, Stanisław Czachórski, Zbigniew Puchała +1
We investigate an original family of quantum distinguishability problems, where the goal is to perfectly distinguish between quantum states that become identical under a comple…
All-sky angular power spectra from cleaned WISESuperCOSMOS galaxy number counts
H. S. Xavier, M. V. Costa-Duarte, A. Balaguera-Antolínez +1
Aiming to extract cosmological information from linear scales of the WISESuperCOSMOS photometric redshift catalog, we perform a characterization of the systematic effects a…
What shapes the Absorption Measure Distribution in AGN outflows
T. P. Adhikari, A. Różańska, K. Hryniewicz +2
The Absorption Measure Distribution (AMD) in the X-ray outflows of Seyfert active galactic nuclei (AGN) describes the distribution of absorbing column density as a function of ioni…
Fidelity susceptibility in Gaussian Random Ensembles
Piotr Sierant, Artur Maksymov, Marek Kuś +1
The fidelity susceptibility measures sensitivity of eigenstates to a change of an external parameter. It has been fruitfully used to pin down quantum phase transitions when applied…
