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…
