AI-Driven Optics Enable 1.4-km Quantum Link Under Strong Turbulence
A research team has demonstrated a 1.4-km free-space quantum link that uses AI-driven adaptive optics to compensate for strong atmospheric turbulence. The system employed machine learning to predict and correct wavefront distortions in real time, preserving the quantum signal. This eliminates the need for complex active alignment hardware typical in free-space quantum communication.

AI-driven adaptive optics could enable robust, low-maintenance urban free-space quantum networks, allowing plug-and-play quantum links between buildings without dedicated alignment infrastructure.
The demonstration under strong turbulence shows ML can handle real-world atmospheric distortion, a primary obstacle. If the approach generalizes to varying conditions and distances up to a few kilometers, it could dramatically simplify deployment of metropolitan QKD networks, making them practical for 24/7 operation.
