Quantum nonlocality in networks can be demonstrated with an arbitrarily small level of independence between the sources
Ivan Šupić, Jean-Daniel Bancal, Nicolas Brunner
Quantum nonlocality can be observed in networks even in the case where every party can only perform a single measurement, i.e. does not receive any input. So far, this effect has b…
Noisy pre-processing facilitating a photonic realisation of device-independent quantum key distribution
M. Ho, P. Sekatski, E. Y. -Z. Tan +3
Device-independent quantum key distribution provides security even when the equipment used to communicate over the quantum channel is largely uncharacterized. An experimental demon…
Algebraic and geometric properties of local transformations
Denis Rosset, Ämin Baumeler, Jean-Daniel Bancal +4
Some properties of physical systems can be characterized from their correlations. In that framework, subsystems are viewed as abstract devices that receive measurement settings as…
Mutually unbiased bases and symmetric informationally complete measurements in Bell experiments
Armin Tavakoli, Máté Farkas, Denis Rosset +2
Mutually unbiased bases (MUBs) and symmetric informationally complete projectors (SICs) are crucial to many conceptual and practical aspects of quantum theory. Here, we develop the…
RepLAB: a computational/numerical approach to representation theory
Denis Rosset, Felipe Montealegre-Mora, Jean-Daniel Bancal
We present a MATLAB/Octave toolbox to decompose finite dimensionial representations of compact groups. Surprisingly, little information about the group and the representation is ne…
What is the minimum CHSH score certifying that a state resembles the singlet?
Xavier Valcarce, Pavel Sekatski, Davide Orsucci +3
A quantum state can be characterized from the violation of a Bell inequality. The well-known CHSH inequality for example can be used to quantify the fidelity (up to local isometrie…
