Photon Fusion Analysis with Imperfect Sources — •Ruolin Guan and Klemens Hammerer — Institut für Theoretische Physik, Leibniz Universität Hannover, Germany

Photon fusion, a process integral to various quantum technologies, relies heavily on the availability of high-quality photon sources. However, real-world implementations often contend with imperfect sources, introducing inefficiencies and challenges in optimizing fusion outcomes. We explore theoretical frameworks and practical simulations to quantify the impact of imperfections on fusion success rate and outcomes. This work enhances the reliability of photon fusion in practical scenarios.
