Certifying non-classicality and non-Gaussianity through optical parametric amplification
Mahmoud Kalash, Marcello H. M. Passos, Ãva Rácz +3
Non-Gaussian states of light are essential for numerous quantum information protocols; thus, certifying non-Gaussianity is crucial. Full quantum state tomography, commonly used for…

Low-coherence interferometry with undetected mid-infrared photons in the high-gain regime
Giovanni Zotti, Dmitri B. Horoshko, Mikhail I. Kolobov +4
We develop a high-parametric-gain SU(1,1) interferometer based on an aperiodically poled Potassium Titanyl Phosphate (apKTP) crystal, enabling frequency-domain low-coherence interf…
