Unified approach to contextuality, non-locality, and temporal correlations
M. Markiewicz, P. Kurzynski, J. Thompson +4
We highlight the existence of a joint probability distribution as the common underpinning assumption behind Bell-type, contextuality, and Leggett-Garg-type tests. We then present a…

Noisy metrology beyond the standard quantum limit
R. Chaves, J. B. Brask, M. Markiewicz +2
Parameter estimation is of fundamental importance in areas from atomic spectroscopy and atomic clocks to gravitational wave detection. Entangled probes provide a significant precis…

Universal scheme for violation of local realism from quantum advantage in one-way communication complexity
L. Czekaj, A. Grudka, M. Horodecki +2
We consider relations between communication complexity problems and detecting correlations (violating local realism) with no local hidden variable model. We show first universal eq…
