Feedback-assisted measurement of the free mass position under the Standard Quantum Limit
G. M. D'Ariano, M. F. Sacchi, R. Seno
The Standard Quantum Limit (SQL) for the measurement of a free mass position is illustrated, along with two necessary conditions for breaching it. A measurement scheme that overcom…
Generation and Measurement of Nonclassical States by Quantum Fock Filter
G. M. D'Ariano, L. Maccone, M. G. A. Paris +1
We study a novel optical setup which is able to select a specific Fock component from a generic input state. The device allows to synthesize number states and superpositions of few…
On the parametric approximation in quantum optics
G. M. D'Ariano, M. G. A. Paris, M. F. Sacchi
We perform the exact numerical diagonalization of the Hamiltonians that describe both degenerate and nondegenerate parametric amplifiers, by exploiting the conservation laws pertai…
