Unifying entanglement and nonclassicality via the Narcowich-Wigner spectrum
Massimo Frigerio, Zacharie Van Herstraeten, Hania Herbi +5
Entanglement and nonclassicality are two fundamental features of quantum mechanics which serve as resources in quantum information processing tasks and are tightly connected by two…
Differential hierarchy of the Husimi representation
Zacharie Van Herstraeten, Ulysse Chabaud
Phase-space representations reveal the geometry of quantum mechanics and distinguish quantum features from classical ones. However, the positivity of a density operator is among th…
Wigner-positive quantum states can have lower entropy than the vacuum
Zacharie Van Herstraeten, Nicolas J. Cerf, Ulysse Chabaud
The Wigner entropy conjecture posits that pure Gaussian states minimize the Shannon entropy of non-negative Wigner functions, known as the Wigner entropy. We show that mixing a spe…
