We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

Quantum information theory has considerably helped in the understanding of quantum many-
body systems. The role of quantum correlations and in particular, bipartite entanglement …

Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

We use entropic uncertainty relations to formulate inequalities that witness Einstein-
Podolsky-Rosen (EPR)-steering correlations in diverse quantum systems. We then use …

Measurements with randomly chosen settings determine many important properties of
quantum states without the need for a shared reference frame or calibration. They naturally …

Recently, an algorithm has been constructed that shows that the binary icosahedral group 2I
together with a T-like gate forms the most efficient single-qubit universal gate set. To carry …

We present a simple family of Bell inequalities applicable to a scenario involving arbitrarily
many parties, each of which performs two binary-outcome measurements. We show that …

We provide several general upper bounds on the rate of a key secure against a quantum
adversary in the device-independent conference key agreement (DI-CKA) scenario. They …

Uncertainty principle lies at the heart of quantum mechanics, while nonlocality is an
intriguing phenomenon of quantum mechanics to rule out local causal theories. One subtle …

We explore the acceleration effect on the genuine tripartite nonlocality (GTN) for one or two
accelerated detector (s) coupled to the vacuum field with initial mixed tripartite states. We …
