Quantum clocks are more precise than classical ones
Mischa P. Woods, Ralph Silva, Gilles Pütz +2
A clock is, from an information-theoretic perspective, a system that emits information about time. One may therefore ask whether the theory of information imposes any constraints o…
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…
Measurement dependent locality
Gilles Pütz, Nicolas Gisin
The demonstration and use of Bell-nonlocality, a concept that is fundamentally striking and is at the core of applications in device independent quantum information processing, rel…
Quantum nonlocality with arbitrary limited detection efficiency
Gilles Pütz, Djeylan Aktas, Anthony Martin +3
The demonstration and use of nonlocality, as defined by Bell's theorem, rely strongly on dealing with non-detection events due to losses and detectors' inefficiencies. Otherwise, t…
Quantum nonlocality with arbitrary limited detection efficiency
Gilles Pütz, Nicolas Gisin
The demonstration and use of nonlocality, as defined by Bell's theorem, rely strongly on dealing with non-detection events due to losses and detector inefficiencies. Otherwise, the…
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…
