Determination of ground state properties in quantum spin systems by single qubit unitary operations and entanglement excitation energies
S. M. Giampaolo, F. Illuminati, P. Verrucchi +1
We introduce a method for analyzing ground state properties of quantum many body systems, based on the characterization of separability and entanglement by single subsystem unitary…
Coexistence of unlimited bipartite and genuine multipartite entanglement: Promiscuous quantum correlations arising from discrete to continuous variable systems
Gerardo Adesso, Marie Ericsson, Fabrizio Illuminati
Quantum mechanics imposes 'monogamy' constraints on the sharing of entanglement. We show that, despite these limitations, entanglement can be fully 'promiscuous', i.e. simultaneous…
Optical state engineering, quantum communication, and robustness of entanglement promiscuity in three-mode Gaussian states
Gerardo Adesso, Alessio Serafini, Fabrizio Illuminati
We present a novel, detailed study on the usefulness of three-mode Gaussian states states for realistic processing of continuous-variable quantum information, with a particular emp…
Monogamy inequality for distributed Gaussian entanglement
Tohya Hiroshima, Gerardo Adesso, Fabrizio Illuminati
We show that for all n-mode Gaussian states of continuous variable systems, the entanglement shared among n parties exhibits the fundamental monogamy property. The monogamy inequal…
Characterizing quantum phase transitions by single qubit operations
S. M. Giampaolo, F. Illuminati, S. De Siena
We introduce observable quantities, borrowing from concepts of quantum information theory, for the characterization of quantum phase transitions in spin systems. These observables…
