According to @ai_darpa, German physicists have successfully teleported quantum data across 79 kilometers using standard internet fiber infrastructure, achieving quantum teleportation beyond controlled laboratory settings (source: @ai_darpa, Dec 26, 2025). By leveraging quantum entanglement, the researchers transferred photon quantum states without physically sending the particles, significantly reducing signal loss and noise. This milestone demonstrates the practical viability of integrating quantum communication with existing telecom networks, paving the way for robust quantum-secure data systems and laying the groundwork for deployable long-distance quantum networking (source: @ai_darpa, Dec 26, 2025). The development holds major implications for AI-driven cybersecurity and next-generation data protection.
