Spatial symmetry in few-photon interference and quantum metrology

Éloi Descamps, Pérola Milman

In previous work [Physical Review Letters, 136(6):060807, 2026], we developed a symmetry-based framework for generalized Hong-Ou-Mandel interference and its applications to quantum…

Non-Gaussianity from superselection rules

Nicolas Moulonguet, Eloi Descamps, José Lorgeré +3

The quantum theory of the electromagnetic field enables the description of multiphoton states exhibiting nonclassical statistical properties, often reflected in non-Gaussian phase-…
