Experimental weak measurement of two non-commuting observables
Gilles Pütz, Tomer Barnea, Nicolas Gisin +1
The fact that not all quantum observables are jointly measurable is one of the major differences between quantum and classical theory. In the former, non-commuting observables can…
Macroscopic Quantum Measurements of noncommuting observables
Tomer Jack Barnea, Marc-Olivier Renou, Florian Fröwis +1
Assuming a well-behaving quantum-to-classical transition, measuring large quantum systems should be highly informative with low measurement-induced disturbance, while the coupling…
Optomechanical Bell test
V. Caprara Vivoli, T. Barnea, C. Galland +1
Photons of a laser beam driving the upper motional sideband of an optomechanical cavity can decay into photon-phonon pairs by means of an optomechanical parametric process. The pho…
Nonlinear Bell inequalities tailored for quantum networks
Denis Rosset, Cyril Branciard, Tomer Jack Barnea +3
In a quantum network, distant observers sharing physical resources emitted by independent sources can establish strong correlations, which defy any classical explanation in terms o…
Nonlocality of and Dicke states subject to losses
Tomer Jack Barnea, Gilles Pütz, Jonatan Bohr Brask +3
We discuss the nonlocality of the and the Dicke states subject to losses. We consider two noise models, namely loss of excitations and loss of particles, and investigate how mu…
Family of Bell-like inequalities as device-independent witnesses for entanglement depth
Yeong-Cherng Liang, Denis Rosset, Jean-Daniel Bancal +3
We present a simple family of Bell inequalities applicable to a scenario involving arbitrarily many parties, each of which performs two binary-outcome measurements. We show that th…
Arbitrarily small amount of measurement independence is sufficient to manifest quantum nonlocality
Gilles Pütz, Denis Rosset, Tomer Jack Barnea +2
The use of Bell's theorem in any application or experiment relies on the assumption of free choice or, more precisely, measurement independence, meaning that the measurements can b…
Tripartite quantum state violating the hidden influence constraints
Tomer Jack Barnea, Jean-Daniel Bancal, Yeong-Cherng Liang +1
The possibility to explain quantum correlations via (possibly) unknown causal influences propagating gradually and continuously at a finite speed v > c has attracted a lot of atten…
