Optical response of a misaligned and suspended Fabry-Perot cavity
G. Cella, A. Di Virgilio, P. La Penna +4
The response to a probe laser beam of a suspended, misaligned and detuned optical cavity is examined. A five degree of freedom model of the fluctuations of the longitudinal and tra…
The Aladin2 experiment: status and perspectives
Giuseppe Bimonte, Detlef Born, Enrico Calloni +7
Aladin2 is an experiment devoted to the first measurement of variations of Casimir energy in a rigid cavity. The main scientific motivation relies on the possibility of the first d…
A theory of electromagnetic fluctuations for metallic surfaces and van der Waals interactions between metallic bodies
Giuseppe Bimonte
A new general expression is derived for the fluctuating electromagnetic field outside a metal surface, in terms of its surface impedance. It provides a generalization to real metal…
On the meaning and interpretation of Tomography in abstract Hilbert spaces
V. I. Man'ko, G. Marmo, A. Simoni +3
The mechanism of describing quantum states by standard probability (tomographic one) instead of wave function or density matrix is elucidated. Quantum tomography is formulated in a…
A new perturbative expansion of the time evolution operator associated with a quantum system
Paolo Aniello
A novel expansion of the evolution operator associated with a -- in general, time-dependent -- perturbed quantum Hamiltonian is presented. It is shown that it has a wide range of p…
Alternative Algebraic Structures from Bi-Hamiltonian Quantum Systems
G. Marmo, G. Scolarici, A. Simoni +1
We discuss the alternative algebraic structures on the manifold of quantum states arising from alternative Hermitian structures associated with quantum bi-Hamiltonian systems. We a…
Wigner distributions for finite dimensional quantum systems: An algebraic approach
S. Chaturvedi, E. Ercolessi, G. Marmo +3
We discuss questions pertaining to the definition of `momentum', `momentum space', `phase space', and `Wigner distributions'; for finite dimensional quantum systems. For such syste…
Massive Quantum Memories by Periodically Inverted Dynamic Evolutions
S. M. Giampaolo, F. Illuminati, A. Di Lisi +1
We introduce a general scheme to realize perfect quantum state reconstruction and storage in systems of interacting qubits. This novel approach is based on the idea of controlling…
Gaussian measures of entanglement versus negativities: the ordering of two-mode Gaussian states
Gerardo Adesso, Fabrizio Illuminati
In this work we focus on entanglement of two--mode Gaussian states of continuous variable systems. We first review the formalism of Gaussian measures of entanglement, adopting the…
Entanglement, Purity, and Information Entropies in Continuous Variable Systems
Gerardo Adesso, Alessio Serafini, Fabrizio Illuminati
Quantum entanglement of pure states of a bipartite system is defined as the amount of local or marginal ({\em i.e.}referring to the subsystems) entropy. For mixed states this ident…
Entanglement sharing: from qubits to Gaussian states
Gerardo Adesso, Fabrizio Illuminati
It is a central trait of quantum information theory that there exist limitations to the free sharing of quantum correlations among multiple parties. Such 'monogamy constraints' hav…
Tomograms in the Quantum-Classical transition
V. I. Man'ko, G. Marmo, A. Simoni +2
The quantum-classical limits for quantum tomograms are studied and compared with the corresponding classical tomograms, using two different definitions for the limit. One is the Pl…
The Schwinger Representation of a Group: Concept and Applications
S. Chaturvedi, G. Marmo, N. Mukunda +2
The concept of the Schwinger Representation of a finite or compact simple Lie group is set up as a multiplicity-free direct sum of all the unitary irreducible representations of th…
An Algebraic Approach to Linear-Optical Schemes for Deterministic Quantum Computing
P. Aniello, R. Coen Cagli
Linear-Optical Passive (LOP) devices and photon counters are sufficient to implement universal quantum computation with single photons, and particular schemes have already been pro…
Differential geometry of density states
V. I. Man'ko, G. Marmo, E. C. G. Sudarshan +1
We consider a geometrization, i.e., we identify geometrical structures, for the space of density states of a quantum system. We also provide few comments on a possible application…
Engineering massive quantum memories by topologically time-modulated spin rings
S. M. Giampaolo, F. Illuminati, A. Di Lisi +1
We introduce a general scheme to realize perfect storage of quantum information in systems of interacting qubits. This novel approach is based on {\it global} external controls of…
Partial positive scaling transform: a separability criterion
Olga V. Manko, V. I. Manko, G. Marmo +3
The problem of constructing a necessary and sufficient condition for establishing the separability of continuous variable systems is revisited. Simon [R. Simon, Phys. Rev. Lett. 84…
