Abstract
Methods and systems are presented for using optical parametric amplifiers in various ways that enhance a native quadratic coupling strength so that a photonic component of interest can be measured or otherwise observed without demolishing the component of interest at a system output. For example such components may include a number of signal Bogoliubov excitations, a pump modular quadrature, or a signal quadrature squared.
