Pauli Encodings & Unclonable Encryption

Pierre Botteron, Sébastien Designolle, Omar Fawzi

The unclonable bit question asks whether quantum encryption can prevent an adversary from producing two systems that both reveal the plaintext once the key is disclosed. We introdu…

Can outcome communication explain Bell nonlocality?

Carlos Vieira, Carlos de Gois, Pedro Lauand +3

A central aspect of quantum information is that correlations between spacelike separated observers sharing entangled states cannot be reproduced by local hidden variable (LHV) mode…

Most incompatible measurements and sum-of-squares optimisation

Sébastien Designolle

Measurement incompatibility, or joint measurability, is a cornerstone of quantum theory and a useful resource. For finite-dimensional systems, quantifying this resource and establi…

A Frank-Wolfe-based primal heuristic for quadratic mixed-integer optimization

Gioni Mexi, Deborah Hendrych, Sébastien Designolle +2

We propose a primal heuristic for quadratic mixed-integer problems. Our method extends the Boscia framework -- originally a mixed-integer convex solver leveraging a Frank-Wolfe-bas…

A Unified Toolbox for Multipartite Entanglement Certification

Ye-Chao Liu, Jannis Halbey, Sebastian Pokutta +1

We present a unified framework for multipartite entanglement characterization based on the conditional gradient (CG) method, incorporating both fast heuristic detection and rigorou…

Measurement incompatibility and quantum steering via linear programming

Lucas E. A. Porto, Sébastien Designolle, Sebastian Pokutta +1

The problem of deciding whether a set of quantum measurements is jointly measurable is known to be equivalent to determining whether a quantum assemblage is unsteerable. This probl…

Efficient Quadratic Corrections for Frank-Wolfe Algorithms

Jannis Halbey, Seta Rakotomandimby, Mathieu Besançon +2

We develop a Frank-Wolfe algorithm with corrective steps, generalizing previous algorithms including blended conditional gradients, blended pairwise conditional gradients, and full…

Improved algorithms and novel applications of the FrankWolfe.jl library

Mathieu Besançon, Sébastien Designolle, Jannis Halbey +6

Frank-Wolfe (FW) algorithms have emerged as an essential class of methods for constrained optimization, especially on large-scale problems. In this paper, we summarize the algorith…

Better bounds on finite-order Grothendieck constants

Sébastien Designolle, Tamás Vértesi, Sebastian Pokutta

Grothendieck constants bound the advantage of -dimensional strategies over -dimensional ones in a specific optimisation task. They have applications ranging from app…

Symmetric multipartite Bell inequalities via Frank-Wolfe algorithms

Sébastien Designolle, Tamás Vértesi, Sebastian Pokutta

In multipartite Bell scenarios, we study the nonlocality robustness of the Greenberger-Horne-Zeilinger (GHZ) state. When each party performs planar measurements forming a regular p…
