Optical Space Communication with Adaptive wavefront Reconstruction using a Pyramidal sensor (OSCAR-Py)

To address the emerging challenges in secure communications, quantum encryption must be integrated into optical communication networks. While significant progress has been made, achieving reliable daytime operation and maintaining high performance under strong atmospheric turbulence remain critical hurdles. In this idea, we propose to investigate the use of a Pyramidal Wavefront Sensor (Py-WFS), combined with artificial intelligence for wavefront reconstruction, to improve fiber coupling efficiency under turbulent conditions and increase the data rate.
