On the emergence of preferred structures in quantum theory
Antoine Soulas, Guilherme Franzmann, Andrea Di Biagio
We assess the possibilities offered by Hilbert space fundamentalism, an attitude towards quantum physics according to which all physical structures (e.g. subsystems, locality, spac…
Disentangling tensor product structures
Antoine Soulas
As a contribution to the field of quantum mereology, we study how a change of tensor product structure in a finite-dimensional Hilbert space affects its entanglement properties. In…
Why is the universe not frozen by the quantum Zeno effect?
Antoine Soulas
We build a discrete model that simulates the ubiquitous competition between the free internal evolution of a two-level system and the decoherence induced by the interaction with it…
A proof that no-signalling implies microcausality in quantum field theory
Antoine Soulas
We study some logical interrelationships between fundamental properties in (relativistic) quantum theories. An operational no-signalling condition is first introduced in the contex…
Quantifying quantum coherence and the deviation from the total probability formula
Antoine Soulas
We propose a novel approach to quantify quantum coherence which, contrary to the previous ones, does not rely on resource theory but rather on ontological considerations. In this f…
