Simulating extremal temporal correlations
Cornelia Spee, Costantino Budroni, Otfried Gühne
The correlations arising from sequential measurements on a single quantum system form a polytope. This is defined by the arrow-of-time (AoT) constraints, meaning that future choice…
Quantum Temporal Superposition: the case of QFT
Laura J. Henderson, Alessio Belenchia, Esteban Castro-Ruiz +4
Quantum field theory is completely characterized by the field correlations between spacetime points. In turn, some of these can be accessed by locally coupling to the field simple…
Memory cost of temporal correlations
Costantino Budroni, Gabriel Fagundes, Matthias Kleinmann
A possible notion of nonclassicality for single systems can be defined on the basis of the notion of memory cost of classically simulating probabilities observed in a temporal sequ…
Device-independent tests of structures of measurement incompatibility
Marco Túlio Quintino, Costantino Budroni, Erik Woodhead +2
In contrast with classical physics, in quantum physics some sets of measurements are incompatible in the sense that they can not be performed simultaneously. Among other applicatio…
Leggett-Garg macrorealism and the quantum nondisturbance conditions
Roope Uola, Giuseppe Vitagliano, Costantino Budroni
We investigate the relation between a refined version of Leggett and Garg conditions for macrorealism, namely the no-signaling-in-time (NSIT) conditions, and the quantum mechanical…
Theoretical research without projects
Miguel Navascues, Costantino Budroni
We propose a funding scheme for theoretical research that does not rely on project proposals, but on recent past scientific productivity. Given a quantitative figure of merit on th…
