On sampling determinantal and Pfaffian point processes on a quantum computer Open
DPPs were introduced by Macchi as a model in quantum optics the 1970s. Since then, they have been widely used as models and subsampling tools in statistics and computer science. Most applications require sampling from a DPP, and given thei…

Testing quantum Darwinism dependence on observers' resources Open
The emergence of an objective classical picture is the core question of quantum Darwinism. How does this reconstructed classical picture depends on the resources available to observers? In this Letter, we develop an experimentally relevant…

From point processes to quantum optics and back Open
Some fifty years ago, in her seminal PhD thesis, Odile Macchi introduced permanental and determinantal point processes. Her initial motivation was to provide models for the set of detection times in fundamental bosonic or fermionic optical…

Einselection from incompatible decoherence channels Open
Decoherence of quantum systems from entanglement with an unmonitored\nenvironment is to date the most compelling explanation of the emergence of a\nclassical picture from a quantum world. While it is well understood for a\nsingle Lindblad …

Time-frequency approach to relativistic correlations in quantum field theory Open
Moving detectors in relativistic quantum field theories reveal the\nfundamental entangled structure of the vacuum which manifests, for instance,\nthrough its thermal character when probed by a uniformly accelerated detector.\nIn this paper…

Intrication et décohérence en Gravité Quantique à boucles Open
Une théorie de gravitation quantique propose de décrire l'interaction gravitationnelle à toutes les échelles de distance et d'énergie. Cependant, comprendre l'émergence de notre espace-temps classique reste un problème toujours ouvert. Cet…

Quantum surface and intertwiner dynamics in loop quantum gravity Open
We introduce simple generic models of surface dynamics in loop quantum\ngravity (LQG). A quantum surface is defined as a set of elementary patches of\narea glued together. We provide it with an extra structure of locality (nearest\nneighbo…
