A Survey on Quantum-Safe Cryptographic Mechanisms: Building Blocks and Applications
Ricardo Parizotto, Preeti Yadav, Marcus Freire +4
The possible emergence of fault-tolerant quantum computers may enable widely used cryptographic algorithms to be broken. These algorithms for public key encryption and digital sign…
Perfect Games in Dimension-Bounded Communication
Emmanuel Zambrini Cruzeiro
Perfect prepare-and-measure games exhibit an all-or-nothing quantum advantage: a quantum system of dimension satisfies every prescribed winning constraint, whereas a classical…
Daylight quantum keyless private communication for free-space links
Pedro Neto Mendes, Preeti Yadav, Lourenço Sumares +3
Quantum key distribution (QKD) is the most established approach in quantum communication. However, long-distance free-space implementations, particularly satellite links, remain ch…
Bell inequalities from outcome equalities
Ricardo Faleiro, Flavien Hirsch, Emmanuel Zambrini Cruzeiro +1
In this work, we study a particular class of Bell inequalities involving only direct equality-comparisons of outcomes. In the bipartite case, the scenario can be interpreted as a n…
Exploring Bell Nonlocality with Extremal Non-Signaling Boxes
Emmanuel Zambrini Cruzeiro, Junior R. Gonzales-Ureta, Raman Choudhary +3
Extremal non-signaling (ENS) boxes are correlations that correspond to vertices of the non-signaling polytope of a Bell scenario. Neither quantum theory nor any theory for ideal me…
