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…
Witnessing Magic with Bell inequalities
Rafael A. Macedo, Patrick Andriolo, Santiago Zamora +2
Non-stabilizerness, or magic, is a fundamental resource for quantum computation, enabling quantum algorithms to surpass classical capabilities. Despite its importance, characterizi…
Experimental quantum randomness enhanced by a quantum network
Emanuele Polino, Luis Villegas-Aguilar, Davide Poderini +10
The certification of randomness is essential for both fundamental science and information technologies. Unlike traditional random number generators, randomness obtained from nonloc…
Error-Correcting Codes in TQFT on Multispheres
Rafael Chaves, Dmitry Melnikov, Marcos Neves +2
Topological quantum field theories (TQFT) encode quantum correlations in topological features of spaces. In this work, we leverage this feature to explore how information encoded i…
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…
