We investigate the correlations that can arise between Alice and Bob in prepare-and-
measure communication scenarios where the source (Alice) and the measurement device …

We consider general prepare-and-measure scenarios in which Alice can transmit qubit
states to Bob, who can perform general measurements in the form of positive operator …

Entanglement and quantum communication are paradigmatic resources in quantum
information science leading to correlations between systems that have no classical …

Nonlocality, as established by the seminal Bell's theorem, is considered to be the most
striking feature of correlations present in spacelike separated events. Its practical application …

Entanglement is known to boost the efficiency of classical communication. In distributed
computation, for instance, exploiting entanglement can reduce the number of communicated …

There are various ways to quantify the communication capabilities of a quantum channel. In
this work we introduce the communication value (cv) of quantum channel, which describes …

Hardy's argument constitutes an elegant proof of quantum nonlocality. In this work, we report
an exotic application of Hardy's nonlocal correlations in two-party communication setup. We …

We implement an experiment on a photonic quantum processor establishing efficacy of the
elementary quantum system in classical information storage. The advantage is established …

Prepare-and-measure scenarios (pm), in their many forms, can be seen as the basic
building blocks of communication tasks. As such, they can be used to analyze a diversity of …

To quantify quantum advantage in communication networks, we apply an operational
framework for witnessing quantum nonclassicality. Following previous approaches in the …
