What are the Challenges in Developing Single Photon Detectors?
Despite their potential, developing single photon detectors entails several challenges. Achieving high detection efficiency, low dark counts (false positives), and fast response times are key technical hurdles. Moreover, integrating these detectors into practical systems while maintaining their performance is complex. Advances in nanofabrication techniques are helping to address these issues, enabling the creation of more reliable and effective detectors.
