Indefinite causal order with output-signalling instruments
Ricardo Silveira, Patrick Andriolo, Davide Poderini +2
Quantum processes can exhibit indefinite causal order, allowing coherent superpositions of distinct orderings of events. Whether such processes generate genuinely noncausal statist…
Sparse positive maps on qutrits with exact nondecomposability thresholds and PPT-entanglement transitions
Davide Poderini, Angela Rosy Morgillo, Fabio Benatti +3
We study a family of sparse positive maps on qutrits for which positivity, decomposability, and PPT entanglement can all be analysed explicitly. The block structure of the associat…
Generating Non-Decomposable Maps with Differentiable Semidefinite Programming
Angela Rosy Morgillo, Davide Poderini, Fabio Anselmi +3
Positive maps that are not decomposable are a key resource in entanglement theory because they can detect bound entangled states, yet systematic methods for constructing them remai…
Network Nonlocality with Separable Measurements
Emanuele Polino, Davide Poderini, Giorgio Minati +3
Quantum correlations in networks with independent sources have revealed novel forms of nonclassical behavior. While entanglement in the sources is a necessary ingredient, the role…
Quantum Hypergraph States: A Review
Davide Poderini, Dagmar Bruß, Chiara Macchiavello
Quantum hypergraph states extend the well-studied class of graph states by taking into account multi-qubit interactions through hyperedges. They provide a powerful framework to rep…
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…
