The Topological Quantum-Entanglement Network (TQEN) is a conceptual next-generation telecommunication architecture proposed for deployment in the 2075–2100 horizon. The work introduces a paradigm shift in global communication by encoding information in topologically protected quantum entanglement correlations rather than classical electromagnetic signal propagation. By leveraging distributed space-time crystal lattices, quantum repeater networks, and topological quantum memory, TQEN aims to overcome fundamental physical and scalability limitations present in fiber-optic, satellite, and existing quantum communication systems. The proposed architecture consists of a three-layer infrastructure including Orbital Quantum Nodes, Terrestrial Gateway Stations, and a Quantum Internet Backbone coordinating entanglement distribution through classical control signaling. The research demonstrates how topological protection can significantly extend quantum coherence lifetimes, enabling globally distributed quantum correlations that support ultra-low latency, high-bandwidth, and inherently secure communication. The paper provides a detailed system architecture, comparative analysis with existing telecommunication paradigms, and a structured multi-phase development roadmap spanning foundational research, prototype space validation, and global deployment. The study also identifies critical scientific barriers, evaluates feasibility using existing experimental breakthroughs in topological photonics and quantum repeaters, and discusses ethical, environmental, and societal implications of a planetary-scale quantum communication infrastructure. TQEN is presented as a long-term, scientifically grounded proposal intended to stimulate interdisciplinary research across quantum information science, photonics, aerospace engineering, and telecommunications.
