Possibilistic approach to network nonlocality
Antoine Restivo, Nicolas Brunner, Denis Rosset
The investigation of Bell nonlocality traditionally relies on joint probabilities of observing certain measurement outcomes. In this work we explore a possibilistic approach, where…
Noncommutative polynomial optimization under symmetry
Marie Ioannou, Denis Rosset
We present a general framework to exploit the symmetries present in the Navascu{é}s-Pironio-Ac{í}n semidefinite relaxations that approximate invariant noncommutative polynomial opt…
Receiver-Device-Independent Quantum Key Distribution Protocols
Marie Ioannou, Pavel Sekatski, Alastair A. Abbott +3
We discuss quantum key distribution protocols and their security analysis, considering a receiver-device-independent (RDI) model. The sender's (Alice's) device is partially charact…
Certifying Numerical Decompositions of Compact Group Representations
Felipe Montealegre-Mora, Denis Rosset, Jean-Daniel Bancal +1
We present a performant and rigorous algorithm for certifying that a matrix is close to being a projection onto an irreducible subspace of a given group representation. This addres…
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…
Postquantum common-cause channels: the resource theory of local operations and shared entanglement
David Schmid, Haoxing Du, Maryam Mudassar +3
We define the type-independent resource theory of local operations and shared entanglement (LOSE). This allows us to formally quantify postquantumness in common-cause scenarios suc…
