Quantum prepare-and-measure scenarios: concepts and methods
A. de Oliveira Junior, Santiago Zamora, Jonatan Bohr Brask +2
Prepare-and-measure scenarios are among the simplest and most widely used settings for quantum communication. A sender prepares a physical system in one of several possible states,…
When Symmetry Suppresses Magic
A. de Oliveira Junior, Jake Xuereb, Rafael A. Macêdo +2
Nonstabilizerness is a critical resource for quantum advantage, but evaluating it, especially for mixed states, requires superexponentially many samples in system size, making the…
A Coherent Search for New Galactic Magnetars using Fermi/GBM and follow-up Swift/BAT: 7 Candidates and a Large Burst Catalog
Ariel Perera, Barak Zackay, Tejaswi Venumadhav
Galactic magnetars are a rare class of neutron stars with extreme magnetic fields, with only about 30 known sources. Their short hard X-ray and soft gamma-ray bursts provide an imp…
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…
