Quantum-secure communications. One sender, one receiver, zero third

Zerothird – Quantum-Secure Communication
At zerothird, we specialize in entanglement-based Quantum Key Distribution (eQKD), ensuring ultra-secure encryption over short and long distances via fiber optics. Our technology, rooted in Nobel Prize–winning research, safeguards critical infrastructure, financial institutions, and government sectors against emerging threats, including quantum attacks. Unlike traditional point-to-point QKD, our entanglement-based system enables high-performance key exchange without security trade-offs. With extended reach up to 300km, seamless multi-user connectivity, and continuous encryption, we provide the most scalable, quantum-safe security solution for the future.
