Network-Irreducible Multiparty Entanglement in Quantum Matter
Liuke Lyu, Pedro Lauand, William Witczak-Krempa
We show that the standard approach to characterize collective entanglement via genuine multiparty entanglement (GME) leads to an area law in ground and thermal Gibbs states of loca…
Can outcome communication explain Bell nonlocality?
Carlos Vieira, Carlos de Gois, Pedro Lauand +3
A central aspect of quantum information is that correlations between spacelike separated observers sharing entangled states cannot be reproduced by local hidden variable (LHV) mode…
Latent splitting as a causal probe
Santiago Zamora, Pedro Lauand, Isadora Veeren +2
Generalizations of Bell's framework to causal networks have yielded new foundational insights and applications, including the use of interventions to enhance the detection of noncl…
Causal Data Fusion with Quantum Confounders
Pedro Lauand, Bereket Ngussie Bekele, Elie Wolfe
From the modern perspective of causal inference, Bell's theorem -- a fundamental signature of quantum theory -- is a particular case where quantum correlations are incompatible wit…
Quantum Non-classicality from Causal Data Fusion
Pedro Lauand, Bereket Ngussie Bekele, Elie Wolfe
Bell's theorem, a cornerstone of quantum theory, shows that quantum correlations are incompatible with a classical theory of cause and effect. Through the lens of causal inference,…
Quantum non-classicality in the simplest causal network
Pedro Lauand, Davide Poderini, Rafael Rabelo +1
Bell's theorem prompts us with a fundamental inquiry: what is the simplest scenario leading to the incompatibility between quantum correlations and the classical theory of causalit…
