Continuity of quantum conditional information
R. Alicki, M. Fannes
We prove continuity of quantum conditional information with respect to the uniform convergence of states and obtain a bound which is independent of the dimension o…
Entanglement swapping of noisy states: A kind of superadditivity in nonclassicality
Aditi Sen De, Ujjwal Sen, Caslav Brukner +2
We address the question as to whether an entangled state that satisfies local realism will give a violation of the same, after entanglement swapping in a suitable scenario. We cons…
Quantification of quantum correlation of ensemble of states
Michal Horodecki, Aditi Sen De, Ujjwal Sen
We present first measure of quantum correlation of an ensemble of multiparty states. It is based on the idea of minimal entropy production in a locally distinguishable basis measur…
Multi-Component Bell Inequality and its Violation for Continuous Variable Systems
Jing-Ling Chen, Chunfeng Wu, L. C. Kwek +3
Multi-component correlation functions are developed by utilizing d-outcome measurements. Based on the multi-component correlation functions, we propose a Bell inequality for bipart…
Secure key from bound entanglement
Karol Horodecki, Michal Horodecki, Pawel Horodecki +1
We characterize the set of shared quantum states which contain a cryptographically private key. This allows us to recast the theory of privacy as a paradigm closely related to that…
Another type of log-periodic oscillations on Polish stock market?
Piotr Gnacinski, Danuta Makowiec
Log-periodic oscillations have been used to predict price trends and crashes on financial markets. So far two types of log-periodic oscillations have been associated with the real…
