Complementarity and correlations
Lorenzo Maccone, Dagmar Bruss, Chiara Macchiavello
We provide an interpretation of entanglement based on classical correlations between measurement outcomes of complementary properties: states that have correlations beyond a certai…
Witnessing entanglement in hybrid systems
Massimo Borrelli, Matteo Rossi, Chiara Macchiavello +1
We extend the definition of entanglement witnesses based on structure factors to the case in which the position of the scatterers is quantized. This allows us to study entanglement…
Hypergraph states in Grover's quantum search algorithm
M. Rossi, D. Bruß, C. Macchiavello
We study the entanglement content of the states employed in the Grover algorithm after the first oracle call when a few searched items are concerned. We then construct a link betwe…
Entanglement and nonclassical properties of hypergraph states
O. Gühne, M. Cuquet, F. E. S. Steinhoff +5
Hypergraph states are multi-qubit states that form a subset of the locally maximally entangleable states and a generalization of the well--established notion of graph states. Mathe…
Randomized Graph States and their Entanglement Properties
Jun-Yi Wu, Matteo Rossi, Hermann Kampermann +4
We introduce a class of mixed multiqubit states, that corresponds to a randomized version of graph states. Such states arise when a graph state is prepared with noisy or imperfect…
