Interpretations of Quantum Mechanics and the measurement problem
M. Genovese
Physics , 2010,
Abstract: We present a panoramic view on various attempts to "solve" the problems of quantum measurement and macro-objectivation, i.e. of the transition from a probabilistic quantum mechanic microscopic world to a deterministic classical macroscopic world.
About entanglement properties of kaons and tests of hidden variables models
M. Genovese
Physics , 2003, DOI: 10.1103/PhysRevA.69.022103
Abstract: In this letter we discuss entanglement properties of neutral kaons systems and their use for testing local realism. In particular we show that, as previous proposals, also a scheme recently suggested for performing a test of hidden variable theories against standard quantum mechanics cannot be conclusive.
Proposal of an experimental scheme for realising a translucent eavesdropping on a quantum cryptographic channel
M. Genovese
Physics , 2000, DOI: 10.1103/PhysRevA.63.044303
Abstract: Purpose of this paper is to suggest a scheme, which can be realised with today's technology and could be used for entangling a probe to a photon qubit based on polarisation. Using this probe a translucent or a coherent eavesdropping can be performed.
Longitudinal and Transverse Nuclear Shadowing
V. Barone,M. Genovese
Physics , 1996,
Abstract: Nuclear shadowing arises from multiple scattering of the hadronic fluctuations of the virtual photon in a nucleus. We predict different longitudinal and transverse shadowing and an A-dependence of R which can be up to a 50% effect. The possibility of detecting nuclear effects on R at HERA is discussed.
On the low x behaviour of nuclear shadowing
V. Barone,M. Genovese
Physics , 1997, DOI: 10.1016/S0370-2693(97)01050-2
Abstract: We calculate the x dependence of nuclear shadowing at moderate values of Q^2 by using HERA diffractive data and, for consistency, F2 parameterization of ZEUS. We show that no decrease of shadowing occurs down to very low x (x = 10^-4).
Quantum non-demolition (QND) modulation of quantum interference
M. Genovese,C. Novero
Physics , 1999, DOI: 10.1103/PhysRevA.61.032102
Abstract: We propose an experiment where quantum interference between two different paths is modulated by means of a QND measurement on one or both the arm of the interferometer. The QND measurement is achieved in a Kerr cell. We illustrate a scheme for the realisation of this experiment and some further developments.
On the generation and identification of optical Schr?dinger cats
M. Genovese,C. Novero
Physics , 2000, DOI: 10.1016/S0375-9601(00)00363-7
Abstract: We discuss the possibility of generating and detecting, by a tomographic reconstruction of the Wigner function, a macroscopic superposition of two coherent states. The superposition state is created using a conditioned measurement on the polarisation of a probe photon entangled to a coherent state. The entanglement is obtained using a Kerr cell inserted in a Mach-Zender interferometer. Some hint about generation of GHZ states is given as well.
Double entanglement and quantum cryptography
M. Genovese,C. Novero
Physics , 2001, DOI: 10.1140/epjd/e2002-00172-5
Abstract: We propose a quantum transmission based on bi-photons which are doubly-entangled both in polarisation and phase. This scheme finds a natural application in quantum cryptography, where we show that an eventual eavesdropper is bound to introduce a larger error on the quantum communication than for a single entangled bi-photon communication, when steeling the same information.
Quantum Clock Synchronisation based on entangled photon pairs transmission
M. Genovese,C. Novero
Physics , 2000,
Abstract: We discuss the possibility of synchronising two atomic clocks exchanging entangled photon pairs through a quantum channel. A proposal for implementing practically such a scheme is discussed.
New schemes for manipulating quantum states using a Kerr cell
M. Genovese,C. Novero
Physics , 2000,
Abstract: In this proceeding we describe various proposals of application of an high coefficient Kerr cell to quantum states manipulation, ranging from fast modulation of quantum interference, GHZ states generation, Schroedinger cats creation, translucent eavesdropping, etc.
