What makes a causal loop consistent?
Hippolyte Dourdent, Andreas Leitherer, Emanuel-Cristian Boghiu +3
Causal loops escape paradoxes if they generate valid probabilities under arbitrary independent local interventions. We show that a deterministic classical process is logically cons…
GPU-accelerated semidefinite programming for causal games
Emanuel-Cristian Boghiu, Kyrylo Simonov
The process matrix formalism describes quantum correlations in scenarios without a fixed causal order between local laboratories. Operational signatures of such correlations can be…
Paradox-free classical non-causality and unambiguous non-locality without entanglement are equivalent
Hippolyte Dourdent, Kyrylo Simonov, Andreas Leitherer +5
Closed timelike curves (CTCs) challenge our conception of causality by allowing information to loop back into its own past. Any consistent description of such scenarios must avoid…
Escaping the Shadow of Bell's Theorem in Network Nonlocality
Maria Ciudad Alañón, Emanuel-Cristian Boghiu, Paolo Abiuso +1
The possibility of nonclassicality in networks unrelated to Bell's original eponymous theorem has recently attracted significant interest. Here, we identify a sufficient condition…
Inflation: a Python library for classical and quantum causal compatibility
Emanuel-Cristian Boghiu, Elie Wolfe, Alejandro Pozas-Kerstjens
We introduce Inflation, a Python library for assessing whether an observed probability distribution is compatible with a causal explanation. This is a central problem in both theor…
Self-organized explosive synchronization in complex networks: Emergence of synchronization bombs
Lluís Arola-Fernández, Sergio Faci-Lázaro, Per Sebastian Skardal +3
We introduce the concept of synchronization bombs as large networks of coupled heterogeneous oscillators that operate in a bistable regime and abruptly transit from incoherence to…
Device-independent and semi-device-independent entanglement certification in broadcast Bell scenarios
Emanuel-Cristian Boghiu, Flavien Hirsch, Pei-Sheng Lin +2
It has recently been shown that by broadcasting the subsystems of a bipartite quantum state, one can activate Bell nonlocality and significantly improve noise tolerance bounds for…
Single-photon nonlocality in quantum networks
Paolo Abiuso, Tamás Kriváchy, Emanuel-Cristian Boghiu +3
The state obtained when a single photon impinges on a balanced beamsplitter is often known as single-photon entangled and its nonlocal properties have been the subject of intense d…
