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…
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…
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…
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…
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…
