Quantum advantages in the prepare-and-measure scenario

The prepare-and-measure scenario is the simplest setting for communication between a sender and a receiver. It serves as a platform both for quantum communication applications and for exploring conceptual aspects of quantum theory. In this talk, I first give an overview of the different semi-device-independent frameworks in which one can analyze quantum communication advantages and cryptography in the prepare-and-measure scenario. Then, I discuss how experiments in this scenario can be used in foundational tests for reference-frame-independent notions of dimensionality and classical stimulability of quantum state ensembles.
