Tradeoff between Wigner negativity and decoherence time for cubic Gaussian states

Matthieu Arnhem, Valerio Crescimanna, Giuseppe Patera +1

Wigner negativity has been shown to be a resource in quantum computing, raising the question of how to efficiently produce states with a large Wigner negativity. Cubic Gaussian sta…

Probabilistic pure state conversion on the majorization lattice

Serge Deside, Matthieu Arnhem, Célia Griffet +1

Entanglement is among the most fundamental-and at the same time puzzling-properties of quantum physics. Its modern description relies on a resource-theoretical approach, which trea…

Interferometric measurement of the quadrature coherence scale using two replicas of a quantum optical state

Célia Griffet, Matthieu Arnhem, Stephan De Bièvre +1

Assessing whether a quantum state is nonclassical (, incompatible with a mixture of coherent states) is a ubiquitous question in quantum optics, yet a nontr…

Multicopy observables for the detection of optically nonclassical states

Matthieu Arnhem, Célia Griffet, Nicolas J. Cerf

Distinguishing quantum states that admit a classical counterpart from those that exhibit nonclassicality has long been a central issue in quantum optics. Finding an implementable c…

Realignment separability criterion assisted with filtration for detecting continuous-variable entanglement

Anaelle Hertz, Matthieu Arnhem, Ali Asadian +1

We introduce a weak form of the realignment separability criterion which is particularly suited to detect continuous-variable entanglement and is physically implementable (it requi…

Optimal estimation of parameters encoded in coherent states quadratures

M. Arnhem, E. Karpov, N. J. Cerf

In the context of multiparameter quantum estimation theory, we investigate the construction of linear schemes in order to infer two classical parameters that are encoded in the qua…
