Generation of macroscopic singlet states in atomic ensembles
Generation macroscopic singlet states atomic ensembles
2010/4/9
We study squeezing of the spin uncertainties by quantum non-demolition (QND) measurement in non-polarized spin ensembles. Unlike the case of polarized ensembles, the QND measurements can be performed ...
CLAS+FROST: new generation of photoproduction experiments at Jefferson Lab.
photoproduction double polarization baryon resonance
2009/11/17
A large part of the experimental program in Hall B of the Jefferson Lab is dedicated to baryon spectroscopy. Photoproduction experiments are essential part of this program. CEBAF Large Acceptance Spec...
Entanglement generation by collisions of quantum solitons
Entanglement generation collisions of quantum solitons
2010/4/13
We present analytic expressions describing generation of the entanglement in collisions of initially uncorrelated quantum solitons. The results, obtained by means of the Born's approximation (for fast...

Optical parametric oscillator Quantum noise Squeezing
2009/6/12
The signal and idler beams from a non-degenerate, above threshold, optical parametric oscillator have a strong quantum correlation, which are called twin beams. This correlation arises from the simult...
