Characterization of quantum devices received from unknown providers is a significant
primary task for any quantum information processing protocol. Self-testing protocols are …

In order to understand the resourcefulness of a natural quantum system in quantum
communication tasks, we study the dense coding capacity (DCC) and teleportation fidelity of …

We study how different types of quantum correlations can be established as the
consequence of a generalized entanglement swapping protocol where, starting from two …

In the tests for macrorealism proposed by Leggett and Garg, the temporal correlation
functions of a dichotomic variable Q must be measured in a noninvasive way to rule out …

We investigate quantum violation of macrorealism for multilevel spin systems under the
condition of coarsening of measurement times, ie, when measurement times have …

We propose a Wigner-like inequality suitable for testing the hypothesis of realism. We show
that this inequality is identical neither to the well-known Wigner inequality nor to the Leggett …

The action of qubit channels on projective measurements on a qubit state is used to
establish an equivalence between channels and properties of generalized measurements …

We explore the fundamental origin of the quantum advantage behind random access code.
We propose new temporal inequalities compatible with noninvasive-realist models and …

The key features of quantum mechanics significantly differ from classical description of
nature. The central concepts underpinning the classical world view are codified through the …

Characterizing multipartite quantum correlations beyond two parties is of utmost importance
for building cutting edge quantum technologies, although the comprehensive picture is still …
