 methods. We then present a quantum-secure architecture with PQC and Quantum Key Distribution (QKD) tailored explicitly for sustainable mobile networks and illustrate its applicability with several use cases that emphasize the need for advanced protection measures in this new era. In addition%2C a comprehensive analysis of PQC algorithm families is presented%2C focusing on their suitability for integration in mobile environments%2C with particular attention to the trade-offs between energy consumption and security improvements. Finally%2C recommendations for strengthening mobile networks against quantum threats are provided through a detailed examination of current challenges and opportunities.)
