Do black holes create polyamory?
Andrzej Grudka, Michael J. W. Hall, Michal Horodecki +3
Of course not, but if one believes that information cannot be destroyed in a theory of quantum gravity, then we run into apparent contradictions with quantum theory when we conside…
The Conditional Uncertainty Principle
Gilad Gour, Andrzej Grudka, Michał Horodecki +3
We develop a general operational framework that formalizes the concept of conditional uncertainty in a measure-independent fashion. Our formalism is built upon a mathematical relat…
Axiomatic approach to contextuality and nonlocality
Karol Horodecki, Andrzej Grudka, Pankaj Joshi +2
We present a unified axiomatic approach to contextuality and non-locality based on the fact that both are resource theories. In those theories the main objects are consistent boxes…
Creation of superposition of unknown quantum states
Michał Oszmaniec, Andrzej Grudka, Michał Horodecki +1
The superposition principle is one of the landmarks of quantum mechanics. The importance of quantum superpositions provokes questions about the limitations that quantum mechanics i…
Quantum communication complexity advantage implies violation of a Bell inequality
Harry Buhrman, Lukasz Czekaj, Andrzej Grudka +5
We obtain a general connection between a quantum advantage in communication complexity and non-locality. We show that given any protocol offering a (sufficiently large) quantum adv…
