Parametric Amplification and Quantum Imaging
This project is aimed at measuring spatial quantum fluctuations in weak images to demonstrate unique quantum properties of image correlation, amplification, and entanglement. We use for this purpose our knowledge on nonlinear imaging and transverse effects in parametric amplification with 
(2) nonlinear crystals.
