We address entanglement, coherence, and information protection in a system of four non-
interacting qubits coupled with different classical environments, namely: common, bipartite …

We introduce a volumetric benchmark for near-term quantum platforms based on the
generation and verification of genuine entanglement across n-qubits using graph states and …

Topological quantum error correcting codes have emerged as leading candidates towards
the goal of achieving large-scale fault-tolerant quantum computers. However, quantifying …

Experimental detection of entanglement certainly disturbs the underlying shared state. It is
possible that the entanglement content of the system is lost in the process of its detection …

Entanglement witnesses (EWs) are a fundamental tool for the detection of entanglement. We
study the inertias of EWs, ie, the triplet of the numbers of negative, zero, and positive …

Variational quantum algorithms (VQAs) have emerged in recent years as a promise to obtain
quantum advantage. These task-oriented algorithms work in a hybrid loop combining a …

We develop a statistical framework, based on a manifold learning embedding, to extract
relevant features of multipartite entanglement structures of mixed quantum states from the …

We investigate the topological-to-non-topological quantum phase transitions (QPTs)
occurring in the Kitaev code under local perturbations in the form of local magnetic field and …

Characterizing large noisy multiparty quantum states using genuine multipartite
entanglement is a challenging task. In this paper, we calculate lower bounds of genuine …

Entanglement witnesses (EWs) are a fundamental tool for the detection of entanglement. We
investigate the inertia of bipartite EWs constructed by the partial transpose of NPT states …
