Nonlocality of<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>W</mml:mi></mml:math>and Dicke states subject to losses

2015 · Physical Review A

We discuss the nonlocality of $W$ and Dicke states subject to losses. We consider two noise models, namely, loss of excitations and loss of particles, and investigate how much loss can be tolerated such that …

Constructing Local Models for General Measurements on Bosonic Gaussian States

2023 · Physical Review Letters

We derive a simple sufficient criterion for the locality of correlations obtained from given measurements on a Gaussian quantum state. The criterion is based on the construction of a local-hidden-variable model that works by passing …
