The rates of several device-independent (DI) protocols, including quantum key-distribution
(QKD) and randomness expansion (RE), can be computed via an optimization of the …

Genuine multipartite non‐locality is not only of fundamental interest but also serves as an
important resource for quantum information theory. The NN‐partite scenario and provide an …

We introduce a hierarchy of tests satisfied by any probability distribution P that represents
the quantum correlations generated in prepare-and-measure (P&M) quantum multichain …

Nonlocal tests on multipartite quantum correlations form the basis of protocols that certify
randomness in a device-independent (DI) way. Such correlations admit a rich structure …

Self-testing is the most accurate form of certification of quantum devices. While self-testing in
bipartite Bell scenarios has been thoroughly studied, self-testing in the more complex …

Randomness certification is a foundational and practical aspect of quantum information
science, essential for securing quantum communication protocols. Traditionally, these …

The certification of randomness is essential for both fundamental science and information
technologies. Unlike traditional random number generators, randomness obtained from …

We establish the profound equivalence between measures of genuine multipartite
entanglement (GME) and their corresponding coherence measures. Initially we construct …

Quantum systems exhibit non-classical correlations that go beyond the capabilities of classi-
cal physics, making these correlations a central focus of research in quantum information …
