According to NightSkyNow on Twitter, researchers have achieved a major milestone by successfully teleporting quantum states of light over active internet fiber cables, even as these cables were carrying regular data traffic (source: NightSkyNow, 2026). This experiment demonstrated quantum teleportation using existing telecommunications infrastructure, leveraging quantum entanglement to transfer quantum information securely. The breakthrough suggests that the development of a quantum internet may not require new hardware installations, presenting substantial business opportunities for telecom and cybersecurity sectors. As quantum communication becomes viable over current networks, enterprises could soon deploy ultra-secure data transmission solutions protected by the laws of physics, reducing the need for traditional encryption and enhancing data privacy. This advancement marks a significant step toward the commercialization of quantum networking and next-generation secure internet services.

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.
