Abstract

The upcoming fifth generation (5G) of wireless networks is expected to lay a foundation of intelligent networks with the provision of some isolated artificial intelligence (AI) operations. However, fully intelligent network orchestration and management for providing innovative services will only be realized in Beyond 5G (B5G) networks. To this end, we envisage that the sixth generation (6G) of wireless networks will be driven by on-demand self-reconfiguration to ensure a many-fold increase in the network performance and service types. The increasingly stringent performance requirements of emerging networks may finally trigger the deployment of some interesting new technologies, such as large intelligent surfaces, electromagnetic-orbital angular momentum, visible light communications, and cell-free communications, to name a few. Our vision for 6G is a massively connected complex network capable of rapidly responding to the users' service calls through real-time learning of the network state as described by the network edge (e.g., base-station locations and cache contents), air interface (e.g., radio spectrum and propagation channel), and the user-side (e.g., battery-life and locations). The multi-state, multi-dimensional nature of the network state, requiring the real-time knowledge, can be viewed as a quantum uncertainty problem. In this regard, the emerging paradigms of machine learning (ML), quantum computing (QC), and quantum ML (QML) and their synergies with communication networks can be considered as core 6G enablers. Considering these potentials, starting with the 5G target services and enabling technologies, we provide a comprehensive review of the related state of the art in the domains of ML (including deep learning), QC, and QML and identify their potential benefits, issues, and use cases for their applications in the B5G networks. Subsequently, we propose a novel QC-assisted and QML-based framework for 6G communication networks while articulating its challenges and potential enabling technologies at the network infrastructure, network edge, air interface, and user end. Finally, some promising future research directions for the quantum- and QML-assisted B5G networks are identified and discussed.

Analysis

Why This Paper Matters

The paper addresses the evolution from 5G to beyond-5G (B5G) and sixth-generation (6G) wireless networks, arguing that fully intelligent network orchestration will require new paradigms beyond classical AI. It positions quantum computing (QC) and quantum machine learning (QML) as core enablers for 6G, motivated by the multi-state, multi-dimensional nature of network state that can be viewed as a quantum uncertainty problem. Given the increasing performance requirements of emerging networks, the paper's vision is timely and influential, as evidenced by its high citation count (647).

The authors provide a comprehensive review of machine learning (including deep learning), QC, and QML, and identify their potential benefits, issues, and use cases for B5G networks. This synthesis is valuable for researchers and practitioners seeking to understand the synergies between these fields and their application to communication networks. The paper also proposes a novel QC-assisted and QML-based framework for 6G, articulating challenges and enabling technologies across network infrastructure, edge, air interface, and user end. This framework serves as a roadmap for future research and development.

Results

As a review and vision paper, it does not present experimental results or quantitative performance metrics. Instead, it offers a conceptual framework and a research agenda. The paper's impact is reflected in its citation count, indicating its influence in shaping the discourse on quantum machine learning for 6G. The authors argue that QML can address the complexity of 6G networks by leveraging quantum parallelism and entanglement, but they do not provide empirical validation.

Significance

The paper is significant for the AI and communications communities as it bridges quantum computing, machine learning, and wireless networks, setting a vision for 6G. It highlights the potential of QML to solve problems that are intractable for classical ML, such as real-time optimization of massive network states. By outlining challenges and future directions, it provides a foundation for subsequent research in quantum-assisted wireless communications. The paper's high citation count underscores its role as a key reference in the emerging field of quantum machine learning for 6G.
