This project investigated the use of quantum-correlated x-rays (QCX) for enhanced x-ray interrogation, and Hong-Ou-Mandel (HOM) metrology was identified as a promising approach.Measurements at the Advanced Photon Source (APS) have conclusively demonstrated the production of correlated x-ray photon pairs, but the project ended before an HOM interferometer could be built. BackgroundThere is a long-standing need within the response community to be able to determine the internal characteristics of an enclosed target.Traditional x-ray techniques provide standoff capability to image the interior of the target and its contents.However, other key attributes can only be determined using methods that require physical contact with the enclosure or contents, which may not be allowable or possible.This project has explored the benefits that QCX may provide.Technical Approach
