1Q: First-Generation Wireless Systems Integrating Classical and Quantum Communication

2025-09-18

AI Summary

Integrating quantum communication with classical wireless networks remains a fundamental challenge, particularly for entanglement distribution over free-space optical (FSO) links. Method: This work proposes 1Q—the first cellular quantum-classical integrated wireless system supporting FSO-based entanglement distribution. It pioneers the adoption of cellular architecture in quantum networking, designing a joint quantum and time-frequency resource scheduling mechanism, and introducing protocols for entanglement generation, distribution, and handover. Key enablers include FSO communication, hybrid resource allocation, quantum error mitigation, and cross-domain protocol adaptation. Contribution: We establish the first scalable quantum cellular network framework, formally defining quantum cells, quantum user equipment, and cross-domain coordination paradigms. We quantitatively characterize coupling constraints among quantum coherence time, entanglement fidelity, and classical-quantum bit-error-rate interdependence. The system fully supports representative quantum applications—including quantum key distribution, blind quantum computation, and distributed quantum sensing—thereby laying a foundational architecture for large-scale wireless quantum internet deployment.

Abstract

We sketch out the concept of 1Q, the first wireless generation of integrated classical and quantum communication. The 1Q framework features quantum base stations (QBSs) that support entanglement distribution via free-space optical links alongside traditional radio communications. Key new components include quantum cells, quantum user equipment (QUEs), and hybrid resource allocation spanning classical time-frequency and quantum entanglement domains. Several application scenarios are discussed and illustrated through system design requirements for quantum key distribution, blind quantum computing, and distributed quantum sensing. A range of unique quantum constraints are identified, including decoherence timing, fidelity requirements, and the interplay between quantum and classical error probabilities. Protocol adaptations extend cellular connection management to incorporate entanglement generation, distribution, and handover procedures, expanding the Quantum Internet to the cellular wireless.
