Quantum optical formulation of difference-frequency generation and optimal cloning of spatial modes
Tanita Permaul, Andrew Forbes, Thomas Konrad
We present a quantum optical formulation of difference-frequency generation (DFG) that incorporates the spatial modes of light. It reproduces the well established result for classi…
