Testing quantum Darwinism dependence on observers' resources

Alexandre Feller, Benjamin Roussel, Adrien Pontlevy +1

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 obser…

From point processes to quantum optics and back

Rémi Bardenet, Alexandre Feller, Jérémie Bouttier +6

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…

Comment on "Strong Quantum Darwinism and Strong Independence are Equivalent to Spectrum Broadcast Structure"

Alexandre Feller, Benjamin Roussel, Irénée Frérot +1

In a recent Letter [Phys. Rev. Lett. 122, 010403 (2019)], an equivalence is proposed between the so-called Spectrum Broadcast Structure for a system-multienvironment quantum state,…

Processing quantum signals carried by electrical currents

Benjamin Roussel, Clément Cabart, Gwendal Fève +1

Recent developments in the coherent manipulation of electrons in ballistic conductors include the generation of time-periodic electrical currents involving one to few electronic ex…

Einselection from incompatible decoherence channels

Alexandre Feller, Guillaume Coeuret Cauquil, Benjamin Roussel

Decoherence of quantum systems from entanglement with an unmonitored environment is to date the most compelling explanation of the emergence of a classical picture from a quantum w…

A time-frequency approach to relativistic correlations in quantum field theory

Benjamin Roussel, Alexandre Feller

Moving detectors in relativistic quantum field theories reveal the fundamental entangled structure of the vacuum which manifests, for instance, through its thermal character when p…
