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,…
Randomness Certification and Trade-offs in the Prepare-and-Broadcast Scenario
Tailan S. Sarubi, Moisés Alves, Vinícius F. Alves +4
We investigate the prepare-and-broadcast scenario, a multipartite extension of dimension-constrained prepare-and-measure experiments in which a quantum system is distributed to mul…
Quantum State Discrimination With Stabilizer Circuits
Benjamin Stratton, Santiago Zamora, Rafael Chaves
The task of quantum state discrimination provides an operational characterization of distinguishability and plays a central role in quantum information science. Since the achievabl…
The Prepare and Broadcast Scenario
Tailan S. Sarubi, Moisés Alves, Santiago Zamora +3
We introduce the dimension-restricted prepare and broadcast (PAB) scenario, which generalizes standard prepare-and-measure frameworks. Here, the system prepared by a sender undergo…
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…
Latent splitting as a causal probe
Santiago Zamora, Pedro Lauand, Isadora Veeren +2
Generalizations of Bell's framework to causal networks have yielded new foundational insights and applications, including the use of interventions to enhance the detection of noncl…
Detection Efficiency Bounds in (Semi-)Device-Independent Scenarios
Tailan S. Sarubi, Santiago Zamora, Moisés Alves +3
This article provides a comprehensive review of the critical role of detection efficiency in demonstrating non-classicality across various device-independent and semi-device-indepe…
Semi-device-independent randomness certification on discretized continuous-variable platforms
Moisés Alves, Vitor L. Sena, Santiago Zamora +4
Randomness is fundamental for secure communication and information processing. While continuous-variable optical systems offer an attractive platform for this task, certifying genu…
Prepare-and-Magic: Semi-Device Independent Magic Certification in the Prepare-and-Measure Scenario
Santiago Zamora, Rafael A. Macedo, Tailan S. Sarubi +3
Non-stabilizerness is an essential resource for quantum computational advantage, as stabilizer states admit efficient classical simulation. We develop a semi-device-independent fra…
A trace distance-based geometric analysis of the stabilizer polytope for few-qubit systems
Alberto B. P. Junior, Santiago Zamora, Rafael A. Macêdo +5
Non-stabilizerness is a fundamental resource for quantum computational advantage, differentiating classically simulable circuits from those capable of universal quantum computation…
Witnessing Magic with Bell inequalities
Rafael A. Macedo, Patrick Andriolo, Santiago Zamora +2
Non-stabilizerness, or magic, is a fundamental resource for quantum computation, enabling quantum algorithms to surpass classical capabilities. Despite its importance, characterizi…
Observational-Interventional Bell Inequalities
Davide Poderini, Ranieri Nery, George Moreno +3
Generalizations of Bell's theorem, particularly within quantum networks, are now being analyzed through the causal inference lens. However, the exploration of interventions, a cent…
