Certification of genuine non-Gaussian entanglement
Lukáš Lachman, Carlos E. Lopetegui-González, Massimo Frigerio +1
Entanglement is a key resource for many quantum applications. Understanding fundamental properties of entangled states is an important step towards their practical exploitation. We…
Interference of photons from independent hot atoms
JaromÃr Mika, Stuti Joshi, Lukáš Lachman +2
The coherence of light from independent ensembles of elementary atomic emitters plays a paramount role in diverse areas of modern optics. We demonstrate the interference of photons…
Hierarchies of quantum non-Gaussian coherences for bosonic systems: A theoretical study
Lukáš Lachman, Beate E. Asenbeck, Ambroise Boyer +4
Quantum coherence in bosonic systems is a fundamental resource for quantum technology applications. In this work, we introduce a framework for analyzing coherence in the Fock-state…
Losses resistant verification of quantum non-Gaussian photon statistics
Riccardo Checchinato, Jan-Heinrich Littmann, Lukáš Lachman +5
Quantum non-Gaussian states of light have fundamental properties that are essential for a multitude of applications in quantum technology. However, many of these features are diffi…
Experimental quantum non-Gaussian coincidences of entangled photons
Run-Ze Liu, Yu-Kun Qiao, Lukáš Lachman +7
Quantum non-Gaussianity, a more potent and highly useful form of nonclassicality, excludes all convex mixtures of Gaussian states and Gaussian parametric processes generating them.…
