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 …

Semi-device-independent characterization of multipartite entanglement of states and measurements

2018 · Physical Review A

The semi-device-independent framework allows one to draw conclusions about properties of an unknown quantum system under weak assumptions. Here we present a semi-device-independent scheme for the characterization of multipartite entanglement based around a game played …

Quantum light : The puzzling predictions of entanglement are coming of age

2015 · Archive ouverte UNIGE (University of Geneva)

Entanglement is the physical property that marks the most striking deviation of the quantum from the classical world. It has been mentioned first by the great Austrian Physicist Erwin Schr¨odinger in 1935 (an introduction to …
