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

Quantum steering refers to the non-classical correlations that can be observed between the
outcomes of measurements applied on half of an entangled state and the resulting post …

Quantum measurements play a fundamental role in quantum mechanics. Especially,
generalized quantum measurements provide a powerful and versatile tool to extract …

One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

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 is built upon the realisation that quantum resources like
coherence and entanglement can be exploited for novel or enhanced ways of transmitting …

Advances in quantum technology require scalable techniques to efficiently extract
information from a quantum system. Traditional tomography is limited to a handful of qubits …

We study the computational complexity of quantum discord (a measure of quantum
correlation beyond entanglement), and prove that computing quantum discord is NP …

We investigate the relation between the incompatibility of quantum measurements and
quantum nonlocality. We show that a set of measurements is not jointly measurable (ie …

" Quantum theory is the soul of theoretical physics. It is not just a theory of specific physical
systems, but rather a new framework with universal applicability. This book shows how we …
