Abstract
The success of many protocols in optical quantum information processing relies on the availability of photon states with a well-defined spatial and temporal mode, but the latter is often difficult to engineer. The authors present a new approach based on nonlinear interferometry that separates the nonlinear gain control from the dispersion engineering, resulting in photon pairs simultaneously possessing the advantages of high purity, high collection efficiency, high brightness, and flexibility in wavelength and bandwidth selection.
