Abstract: Space-to-ground optical communication (STGOC) utilizes laser beams to establish bidirectional links between satellites and ground stations (GSs), which are sensitive to cloud blockage. In ...

A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending ...

Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...

Abstract: The evolution of communication network architectures is steering towards more sustainable, flexible, and lightweight designs, particularly with the advent of sixth-generation (6G) mobile ...
