Abstract: This paper introduces a physical layer encryption scheme in 100 Gb/s inter-satellite coherent optical communication systems based on the dual polarization in-phase and quadrature (DP-IQ) ...

Abstract: The rapid growth of digital media has increased the need to protect image data from unauthorized access, particularly in fields such as medical imaging, military communication, and online ...

The breakthrough addresses concerns that powerful quantum computers could eventually crack encryption standards to leave vulnerable financial systems, government communications, health data and media.
