Quantum technologies rely on phenomena such as superposition, entanglement, and quantum interference to unlock unprecedented capabilities. Over the past decade, we have witnessed significant progress in quantum key distribution (QKD), quantum computing prototypes, and entanglement-based networking. However, numerous technical, theoretical, and engineering challenges remain before these systems can be fully scaled, secured, and standardized.
With growing interest in quantum internet architectures, hybrid quantum-classical systems, and quantum AI, the need for cross-disciplinary research and global collaboration has never been greater. This Research Topic aims to map the evolving terrain of quantum innovation.
The goal of this Research Topic is to provide a comprehensive platform for exploring the state-of-the-art and future directions of quantum technologies. As quantum systems become increasingly integrated into practical applications, it is essential to build a shared understanding across subdomains of communication, computation, and control.
This collection seeks to highlight innovative solutions to current challenges—such as scalability, error correction, decoherence, quantum channel modeling, and integration with classical systems. Furthermore, it aims to foster collaboration between theoretical and experimental communities to accelerate the deployment of quantum-enabled infrastructure and services.
