QKD: FROM THE LAB INTO INDUSTRIAL IMPLEMENTATION I am deeply impressed by Terra Quantum AG’s persistence, focus, and long-term strategic execution. What began as a bold vision is now becoming an industrial reality. In May 2023, we published a groundbreaking new Quantum Key Distribution (#QKD) protocol in Nature Portfolio, titled “Forty Thousand Kilometers Under Quantum Protection.” Developed in our Terra Quantum AG labs, it became one of the most downloaded scientific papers of the year. This work paved the way for a global benchmark in QKD. A protocol that can be seamlessly implemented into existing optical fiber infrastructures, making it the only technically viable and cost-efficient path toward large-scale quantum-secure communication. Now, in October 2025, we have reached the next milestone. Our latest paper, “Loss control-based QKD with noisy devices,” has again been published in Nature Portfolio. This breakthrough takes QKD from theory to real-world application. It proves that quantum communication remains secure and efficient even under realistic, noisy conditions, a crucial step toward industrial deployment of quantum-secure networks. Together, these achievements demonstrate what we at Terra Quantum AG have always believed. Quantum technology is no longer experimental, it is ready for implementation at scale.
