Noise level of a ring laser gyroscope in the femto-rad/s range
Angela D. V. Di Virgilio, Francesco Bajardi, Andrea Basti +10
Absolute angular rotation rate measurements with sensitivity better than prad/s would be beneficial for fundamental science investigations. On this regard, large frame Earth based…
Distributing CV entanglement over 4 co-propagating orthogonal modes
A. Pecoraro, A. Porzio
We propose a scheme for distributing continuous variable entanglement originally established among a pair of mode between a set of four orthogonal co-propagating modes. This is acc…
Continuous-Variable Entangled States of Light carrying Orbital Angular Momentum
A. Pecoraro, F. Cardano, L. Marrucci +1
The orbital angular momentum of light, unlike spin, is an infinite-dimensional discrete variable and may hence offer enhanced performances for encoding, transmitting, and processin…
Experimental pre-assessing entanglement in Gaussian states mixing
A. Pecoraro, D. Buono, G. Nocerino +3
We suggest and demonstrate a method to assess entanglement generation schemes based on mixing of Gaussian states at a beam splitter (BS). Our method is based on the fidelity criter…
Inconstant Planck's constant
Gianpiero Mangano, Fedele Lizzi, Alberto Porzio
Motivated by the Dirac idea that fundamental constant are dynamical variables and by conjectures on quantum structure of spacetime at small distances, we consider the possibility t…
Different operational meanings of continuous variable Gaussian entanglement criteria and Bell inequalities
D. Buono, G. Nocerino, S. Solimeno +1
Entanglement, one of the most intriguing aspects of quantum mechanics, marks itself into different features of quantum states. For this reason different criteria can be used for ve…
