We present in detail a statistical approach for the reference-frame-independent detection
and characterization of multipartite entanglement based on moments of randomly measured …

The existence of correlations between the parts of a quantum system on the one hand, and
entanglement between them on the other, are different properties. Yet, one intuitively would …

Throughout its history, the theory of quantum error correction has heavily benefited from
translating classical concepts into the quantum setting. In particular, classical notions of …

Correlations in multiparticle systems are constrained by restrictions from quantum
mechanics. A prominent example for these restrictions are monogamy relations, limiting the …

It has been demonstrated both theoretically and experimentally that genuine multipartite
entanglement between qubits can exist even in the absence of multipartite correlations …

Peculiarities of multiqubit measurement are for the most part similar to peculiarities of
measurement for qudit—quantum object with finite-dimensional Hilbert space. Three …

The detection of entanglement of systems with many constituents usually requires a large
number of measurements. The number of measurements can be reduced by finding …

Problemet med provtagning av utdata från kvantkretsar har föreslagits som en kandidat för
att visa en kvantberäkningsfördel (ibland kallad kvant” överlägsenhet”). I detta arbete …

Los algoritmos cuánticos variacionales (VQA) se consideran algunos de los métodos más
prometedores para determinar las propiedades de sistemas cuánticos complejos de …
