recommendations! Published in 2019 at "Journal of Physics A: Mathematical and Theoretical"

DOI: 10.1088/1751-8121/aafde7

Abstract: The prepare-and-measure scenario offers the possibility to infer the dimension of an unknown physical system in a device-independent way, i.e. using only raw measurement data with apparatuses regarded as black boxes. We provide here a… read more here.

DOI: 10.1103/physreva.98.062307

Abstract: The goal of self-testing is to characterize an a priori unknown quantum system based solely on measurement statistics, i.e. using an uncharacterized measurement device. Here we develop self-testing methods for quantum prepare-and-measure experiments, thus not… read more here.

DOI: 10.1103/physrevlett.126.210503

Abstract: A semi-device-independent framework for prepare-and-measure experiments is introduced in which an experimenter can tune the degree of distrust in the performance of the quantum devices. In this framework, a receiver operates an uncharacterized measurement device… read more here.

DOI: 10.1103/physrevlett.129.250504

Abstract: Quantum communication is often investigated in scenarios where only the dimension of Hilbert space is known. However, assigning a precise dimension is often an approximation of what is actually a higher-dimensional process. Here, we introduce… read more here.
