Harmonic entanglement from second-order nonlinearity: optimization and interpretation
Nicolai B. Grosse, Syed M. Assad, Moritz Mehmet, Thomas Symul, Ping Koy Lam · 2007
We theoretically investigate EPR entanglement in continuous-variable quadrature measurements between the fundamental and second-harmonic fields generated in the degenerate second-order nonlinear optical process. The parameters that optimize entanglement are found.
