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…

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…

Entanglement distribution in quantum networks via swapping of partially entangled pure states

Henrique Guerra, Tailan S. Sarubi, Rafael Chaves +1

The entanglement swapping protocol (ESP) is a fundamental primitive for distributing quantum correlations across distant nodes in a quantum network. Recent studies have demonstrate…
