Towards a tomographic picture of a Bose-Einstein condensate
Stefano Mancini, Mauro Fortunato, Paolo Tombesi +1
We investigate by means of numerical simulations the possibilities of tomographic techniques applied to a Bose-Einstein condensate in order to reconstruct its ground state. Essenti…
The Pauli Equation for Probability Distributions
S. Mancini, O. V. Man'ko, V. I. Man'ko +1
The "marginal" distributions for measurable coordinate and spin projection is introduced. Then, the analog of the Pauli equation for spin-1/2 particle is obtained for such probabil…
Optomechanical tailoring of quantum fluctuations
S. Mancini, H. M. Wiseman
We propose the use of feedback mechanism to control the level of quantum noise in a radiation field emerging from a pendular Fabry-Perot cavity. It is based on the possibility to p…
Quantum Logic with a Single Trapped Electron
S. Mancini, A. M. Martins, P. Tombesi
We propose the use of a trapped electron to implement quantum logic operations. The fundamental controlled-NOT gate is shown to be feasible. The two quantum bits are stored in the…
Spectrum of light scattered from a deformed Bose-Einstein condensate
S. Mancini, V. I. Man'ko
The spectrum of light scattered from a Bose-Einstein condensate is studied in the limit of particle-number conservation. To this end, a description in terms of deformed bosons is i…
Parametric image amplification in optical cavities
S. Mancini, A. Gatti, L. A. Lugiato
We show the possibility of noiseless amplification of an optical image in cavities containing a parametric oscillator. We consider a confocal ring cavity with plane mirrors and com…
