Enhancing noise robustness in device-independent conference key agreement with asymmetric parity-CHSH inequalities
Makoto Ishihara, Wojciech Roga, Jonatan Bohr Brask +1
Conference key agreement allows multiple remote parties to establish a shared secret key with information-theoretical security. In device-independent conference key agreement, secu…
Every Little Thing Heat Does Is Magic
Rafael A. Macêdo, A. de Oliveira Junior, Naim E. Comar +4
How can one certify that an unknown quantum state possesses magic without resorting to full state tomography? We address this question by introducing two thermodynamic witnesses th…
Quantum correlations in prepare-and-measure scenarios and their semi-device-independent applications
Jonatan Bohr Brask, Nicolas Brunner, Jef Pauwels +2
A key aspect in quantum information is to understand the advantage offered by quantum systems over classical ones in communication tasks. In recent years, a fundamental approach to…
Robust Bell Nonlocality from Gottesman-Kitaev-Preskill States
Xiaotian Yang, Santiago Zamora, Rafael Chaves +3
Bell tests based on homodyne detection are strongly constrained in continuous-variable systems. Can Gottesman-Kitaev-Preskill (GKP) encoding turn homodyne detection into a practica…
