Witnessing the non-objectivity of an unknown quantum dynamics

Davide Poderini, Giovanni Rodari, George Moreno +6

Quantum Darwinism offers an explanation for the emergence of classical objective features -- those we are used to at macroscopic scales -- from quantum properties at the microscopi…

Witnessing Non-Classicality in a Simple Causal Structure with Three Observable Variables

Pedro Lauand, Davide Poderini, Ranieri Nery +4

Seen from the modern lens of causal inference, Bell's theorem is nothing else than the proof that a specific classical causal model cannot explain quantum correlations. It is thus…

Quantifying Quantum Causal Influences

Lucas Hutter, Rafael Chaves, Ranieri Nery +2

Causal influences are at the core of any empirical science, the reason why its quantification is of paramount relevance for the mathematical theory of causality and applications. Q…

Experimental nonclassicality in a causal network without assuming freedom of choice

Emanuele Polino, Davide Poderini, Giovanni Rodari +10

In a Bell experiment, it is natural to seek a causal account of correlations wherein only a common cause acts on the outcomes. For this causal structure, Bell inequality violations…

Events in quantum mechanics are maximally non-absolute

George Moreno, Ranieri Nery, Cristhiano Duarte +1

The notorious quantum measurement problem brings out the difficulty to reconcile two quantum postulates: the unitary evolution of closed quantum systems and the wave-function colla…

Causal inference with imperfect instrumental variables

Nikolai Miklin, Mariami Gachechiladze, George Moreno +1

Instrumental variables allow for quantification of cause and effect relationships even in the absence of interventions. To achieve this, a number of causal assumptions must be met,…

Enhancing entanglement and total correlations dynamics via local unitaries

Joab Morais Varela, Ranieri Nery, George Moreno +3

The interaction with the environment is one of the main obstacles to be circumvented in practical implementations of quantum information tasks. The use of local unitaries, while no…

Quantum communication complexity beyond Bell nonlocality

Joseph Ho, George Moreno, Samuraí Brito +8

Efficient distributed computing offers a scalable strategy for solving resource-demanding tasks such as parallel computation and circuit optimisation. Crucially, the communication…

Causal Networks and Freedom of Choice in Bell's Theorem

Rafael Chaves, George Moreno, Emanuele Polino +9

Bell's theorem is typically understood as the proof that quantum theory is incompatible with local-hidden-variable models. More generally, we can see the violation of a Bell inequa…

Semi-device-independent certification of entanglement in superdense coding

George Moreno, Ranieri Nery, Carlos de Gois +2

Superdense coding is a paradigmatic protocol in quantum information science, employing a quantum communication channel to send classical information more efficiently. As we show he…

General Method for Classicality Certification in the Prepare and Measure Scenario

Carlos de Gois, George Moreno, Ranieri Nery +3

Preparation and measurement of physical systems are the operational building blocks of any physical experiment, and to describe them is the first purpose of any physical theory. It…

Multistage games and Bell scenarios with communication

George Moreno, Ranieri Nery, Alberto Palhares +1

Bell nonlocality is a cornerstone of quantum theory with applications in information processing ranging from cryptography to distributed computing and game theory. Indeed, it is kn…
