Quantum Kolmogorov complexity and quantum correlations in deterministic-control quantum Turing machines
Mariano Lemus, Ricardo Faleiro, Paulo Mateus +2
This work presents a study of Kolmogorov complexity for general quantum states from the perspective of deterministic-control quantum Turing Machines (dcq-TM). We extend the dcq-TM…
Connecting XOR and XOR* games
Lorenzo Catani, Ricardo Faleiro, Pierre-Emmanuel Emeriau +2
In this work we focus on two classes of games: XOR nonlocal games and XOR* sequential games with monopartite resources. XOR games have been widely studied in the literature of nonl…
Device-independent quantum authorization based on the Clauser-Horne-Shimony-Holt game
Ricardo Faleiro, Manuel Goulão
In the spirit of device-independent cryptography, we present a two-party quantum authorization primitive with non-locality as its fueling resource. Therein, users are attributed au…
A coherence-witnessing game and applications to semi-device-independent quantum key distribution
Mário Silva, Ricardo Faleiro, Paulo Mateus +1
Semi-device-independent quantum key distribution aims to achieve a balance between the highest level of security, device independence, and experimental feasibility. Semi-quantum ke…
Operational interpretation of the vacuum and process matrices for identical particles
Ricardo Faleiro, Nikola Paunkovic, Marko Vojinovic
This work overviews the single-particle two-way communication protocol recently introduced by del Santo and Dakić (dSD), and analyses it using the process matrix formalism. We give…
Entanglement of Vacuum States With the de Sitter Horizon: Consequences on Holographic Dark Energy
Rafael Pavão, Ricardo Faleiro, Alex H. Blin +1
The aim of this article is to study the effect of an Event Horizon on the entanglement of the Quantum Vacuum and how entanglement, together with the Holographic Principle, may expl…
Momentum correlations of scattered particles in quantum field theory: one-loop entanglement generation
Ricardo Faleiro, Rafael Pavão, Helder Alexander +3
We compute the entanglement entropy variation between initial (separable or entangled in the momenta) and final states in an elastic scattering of a bipartite system compose…
