Robustness against parametric noise of non ideal holonomic gates
Cosmo Lupo, Paolo Aniello, Mario Napolitano +1
Holonomic gates for quantum computation are commonly considered to be robust against certain kinds of parametric noise, the very motivation of this robustness being the geometric c…
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…
Star products, duality and double Lie algebras
Olga V. Man'ko, Vladimir I. Man'ko, Giuseppe Marmo +1
Quantization of classical systems using the star-product of symbols of observables is discussed. In the star-product scheme an analysis of dual structures is performed and a physic…
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…
New uncertainty relations for tomographic entropy: Application to squeezed states and solitons
Sergio De Nicola, Renato Fedele, Margarita A. Man'ko +1
Using the tomographic probability distribution (symplectic tomogram) describing the quantum state (instead of the wave function or density matrix) and properties of recently introd…
The Aladin2 experiment: sensitivity study
Giuseppe Bimonte, Detlef Born, Enrico Calloni +7
Aladin2 is an experiment devoted to the first measurement of variations of Casimir energy in a rigid body. The main short-term scientific motivation relies on the possibility of th…
Engineering multiphoton states for linear optics computation
Paolo Aniello, Cosmo Lupo, Mario Napolitano +1
Transformations achievable by linear optical components allow to generate the whole unitary group only when restricted to the one-photon subspace of a multimode Fock space. In this…
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…
Does The Uncertainty Relation Determine The Quantum State?
Olga V. Man'ko, V. I. Man'ko, G. Marmo +2
The example of nonpositive trace-class Hermitian operator for which Robertson-Schroedinger uncertainty relation is fulfilled is presented. The partial scaling criterion of separabi…
Tomography in abstract Hilbert spaces
V. I. Man'ko, G. Marmo, A. Simoni +1
The tomographic description of a quantum state is formulated in an abstract infinite dimensional Hilbert space framework, the space of the Hilbert-Schmidt linear operators, with tr…
A tomographic setting for quasi-distribution functions
V. I. Man'ko, G. Marmo, A. Simoni +2
The method of constructing the tomographic probability distributions describing quantum states in parallel with density operators is presented. Known examples of Husimi-Kano quasi-…
Relations Between Quantum Maps and Quantum States
M. Asorey, A. Kossakowski, G. Marmo +1
The relation between completely positive maps and compound states is investigated in terms of the notion of quantum conditional probability.
Comment on " Low-frequency character of the Casimir force between metallic films"
Giuseppe Bimonte
In Phys. Rev. {\bf E 70}, 047102 (2004), J.R. Torgerson and S.K. Lamoreaux investigated for the first time the real-frequency spectrum of finite temperature correction to the Casim…
Entanglement in Gaussian matrix-product states
Gerardo Adesso, Marie Ericsson
Gaussian matrix product states are obtained as the outputs of projection operations from an ancillary space of M infinitely entangled bonds connecting neighboring sites, applied at…
