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

Nonlocality was discovered by John Bell in 1964, in the context of the debates about
quantum theory, but is a phenomenon that can be studied in its own right. Its observation …

Measurements performed on distant parts of an entangled quantum state can generate
correlations incompatible with classical theories respecting the assumption of local …

Measurement incompatibility is the most basic resource that distinguishes quantum from
classical physics. Contextuality is the critical resource behind the power of some models of …

We propose an optimal and efficient numerical test for witnessing genuine multipartite
nonlocality based on a geometric approach. In particular, we consider two non-equivalent …

Incompatibility of observables, or measurements, is one of the key features of quantum
mechanics, related, among other concepts, to Heisenberg's uncertainty relations and Bell …

We employ a trapped ion to study quantum contextual correlations in a single qutrit using the
5-observable Klyachko, Can, Binicioğlu, and Shumovsky inequality, which is arguably the …

Quantum nonlocality and the uncertainty principle are two fundamental cornerstones of
quantum theory, reflecting totally different aspects that distinguish it from classical theory …

We study the set of almost-quantum correlations and their refinements in the simplest
tripartite Bell scenario where each party is allowed to perform two dichotomic …

We designed a quantum circuit to prepare a permutation-symmetric maximally entangled
three-qubit state called the $\vert {\rm S}\rangle $ state and experimentally created it on an …
