As artificial intelligence drives an explosion in global data traffic, researchers have developed a new optical transmission system that could secure tomorrow's data networks against quantum-era cyber threats while reducing energy use and boosting speed.

Published in Advanced Photonics, the study introduces a quantum-secured data transmission architecture that minimizes digital signal processing (DSP) demands while achieving terabit-per-second data rates. The system is designed to meet the stringent speed, efficiency, and security requirements of AI-driven data center interconnects.

"Our work paves the way for the next generation of secure, scalable, and cost-efficient optical interconnects, protecting AI-driven data centers against quantum security threats while meeting the high demands
