A tomographic measurement is a ubiquitous tool for estimating the properties of quantum
states, and its application is known as quantum state tomography (QST). The process …

Dense coding is the seminal example of how entanglement can boost qubit communication,
from sending one bit to sending two bits. This is made possible by projecting separate …

The goal of self-testing is to characterize an a priori unknown quantum system based solely
on measurement statistics, ie, using an uncharacterized measurement device. Here we …

The semi-device-independent approach provides a framework for prepare-and-measure
quantum protocols using devices whose behavior must not be characterized nor trusted …

We consider the problem of testing the dimension of uncharacterized classical and quantum
systems in a prepare-and-measure setup. Here we assume the preparation and …

Self-testing represents the strongest form of certification of a quantum system. Here, we
theoretically and experimentally investigate self-testing of nonprojective quantum …

Dimension witnesses allow one to test the dimension of an unknown physical system in a
device-independent manner, that is, without placing assumptions about the functioning of …

Of late, there has been an upsurge of interest in studying the sequential sharing of various
forms of quantum correlations, viz., nonlocality, preparation contextuality, coherence, and …

Leggett and Garg formulated macrorealist models encoding our intuition on classical
systems, ie, physical quantities have a definite value that can be measured with minimal …
