Multivariate Rényi divergences characterise betting games with multiple lotteries
Andrés F. Ducuara, Erkka Haapasalo, Ryo Takakura
We provide an operational interpretation of the multivariate Rényi divergence in terms of economic-theoretic tasks based on betting, risk aversion, and multiple lotteries. We show…
All incompatible sets of measurements can generate Buscemi nonlocality
Andrés F. Ducuara, Patryk Lipka-Bartosik, Cristian E. Susa +1
The presence of Bell-nonlocality in the correlations arising from measuring spatially-separated systems guarantees that the sets of measurements used are necessarily incompatible.…
Multi-object operational tasks for measurement incompatibility
Andrés F. Ducuara, Ryo Takakura, Fernando J. Hernandez +1
We introduce multi-object operational tasks for measurement incompatibility in the form of multi-object quantum subchannel discrimination and exclusion games with prior information…
Locally inaccessible hidden quantum correlations
Andrés F. Ducuara, Cristian E. Susa, Paul Skrzypczyk
We prove, modulo a conjecture on quantum steering ellipsoids being true, the existence of the phenomenon of locally inaccessible hidden quantum correlations. That is, the existence…
Swapping of quantum correlations and the role of local filtering operations
Pedro Rosario, Andrés F. Ducuara, Cristian E. Susa
We address the swapping of various quantum correlation measures including: Bell-nonlocality, EPR-steering, usefulness for teleportation, entanglement, quantum obesity, as well as t…
Quantum steering and quantum discord under noisy channels and entanglement swapping
Pedro Rosario, Andrés F. Ducuara, Cristian E. Susa
Quantum entanglement, discord, and EPR-steering are properties which are considered as valuable resources for fuelling quantum information-theoretic protocols. EPR-steering is a pr…
Characterisation of quantum betting tasks in terms of Arimoto mutual information
Andres F. Ducuara, Paul Skrzypczyk
We introduce operational quantum tasks based on betting with risk-aversion -- or quantum betting tasks for short -- inspired by standard quantum state discrimination and classical…
The operational significance of the quantum resource theory of Buscemi nonlocality
Patryk Lipka-Bartosik, Andrés Ducuara, Tom Purves +1
Although entanglement is necessary for observing nonlocality in a Bell experiment, there are entangled states which can never be used to demonstrate nonlocal correlations. In a sem…
Emergence of maximal hidden quantum correlations and its trade-off with the filtering probability in dissipative two-qubit systems
Andrés F. Ducuara, Cristian E. Susa, John H. Reina
We investigate the behaviour of quantum CHSH-nonlocality, -steering, and usefulness for teleportation in an interacting two-qubit dissipative system. We show regimes where…
Multi-object operational tasks for convex quantum resource theories
Andrés F. Ducuara, Patryk Lipka-Bartosik, Paul Skrzypczyk
The prevalent modus operandi within the framework of quantum resource theories has been to characterise and harness the resources within single objects, in what we can call \emph{s…
Operational interpretation of weight-based resource quantifiers in convex quantum resource theories of states
Andrés F. Ducuara, Paul Skrzypczyk
We introduce the resource quantifier of weight of resource for convex quantum resource theories of states with arbitrary resources. We show that it captures the advantage that a re…
Weight of informativeness, state exclusion games and excludible information
Andrés F. Ducuara, Paul Skrzypczyk
We consider the quantum resource theory of measurement informativeness and introduce a weight-based quantifier of informativeness. We show that this quantifier has operational sign…
On the Activation of Quantum Nonlocality
Andrés F. Ducuara, Javier Madroñero, John H. Reina
We report on some quantum properties of physical systems, namely, entanglement, nonlocality, -copy nonlocality (superactivation of nonlocality), hidden nonlocality (activation o…
Quantum Locality in Game Strategy
Carlos A. Melo-Luna, Cristian E. Susa, Andres F. Ducuara +2
Game theory is a well established branch of mathematics whose formalism has a vast range of applications from the social sciences, biology, to economics. Motivated by quantum infor…
Not-Post-Peierls compatibility under noisy channels
Andrés F. Ducuara, Cristian E. Susa, John H. Reina
The Pusey-Barrett-Rudolph (PBR) theorem deals with the realism of the quantum states. It establishes that every pure quantum state is real, in the context of quantum ontological mo…
