Semidefinite programs are convex optimization problems involving a linear objective
function and a domain of positive-semidefinite matrices. Over the past two decades, they …

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 …

Losses in the transmission channel, which increase with distance, pose a major obstacle to
photonics demonstrations of quantum nonlocality and its applications. Recently, Chaturvedi …

Harnessing the advantages of shared entanglement for sending quantum messages often
requires the implementation of complex two-particle entangled measurements. We …

Self-testing is a promising approach to certifying quantum states or measurements.
Originally, it relied solely on the outcome statistics of the measurements involved in a device …

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 …

Self-testing is a powerful method for certifying quantum systems. Initially proposed in the
device-independent (DI) setting, self-testing has since been relaxed to the semi-device …

We show that weakly entangled states can improve communication over a qubit channel
using only separate, interference-free, measurements of individual photons. We introduce a …

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

Few primitives are as intertwined with the foundations of cryptography as Oblivious Transfer
(OT). Not surprisingly, with the advent of the use of quantum resources in information …
