This article presents a general discussion of several aspects of our present understanding of
quantum mechanics. The emphasis is put on the very special correlations that this theory …

The laws of nature have come a long way since the time of Newton: quantum mechanics
and relativity have given us good reasons to take seriously the possibility of laws which may …

Recently, it has been shown that at most two observers (Bobs) can sequentially demonstrate
bipartite nonlocality with a spatially separated single observer (Alice) invoking a scenario …

We describe a new technique for obtaining Tsirelson bounds, which are upper bounds on
the quantum value of a Bell inequality. Since quantum correlations do not allow signalling …

Machine learning, the core of artificial intelligence and big data science, is one of today's
most rapidly growing interdisciplinary fields. Recently, machine learning tools and …

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

Quantum mechanics puts a restriction on the number of observers who can simultaneously
steer another observer's system, known as the monogamy of steering. In this work, we find …

We consider the characterization of entanglement depth in a quantum many-body system
from the device-independent perspective; that is, we aim at certifying how many particles are …

Standard tripartite nonlocality and genuine tripartite nonlocality can be detected by the
violations of Mermin inequality and Svetlichny inequality, respectively. Since tripartite …

A fruitful way of studying physical theories is via the question whether the possible physical
states and different kinds of correlations in each theory can be shared to different parties …
