With the increasing number of commercial 5G deployments, research on beyond 5G (B5G) and 6G has started in earnest. Although it is too early to clearly identify what 6G systems will look like or how they will be designed, it is certain that 6G systems will support novel use cases with challenging key performance indicators (KPIs), which will be empowered by new enabling technologies and network architectures. In parallel with the evolution of cellular systems from 5G toward 6G, quantum information technology (QIT) has been evolving rapidly in recent years in terms of quantum communications and quantum computing. It is envisioned that QIT will enable and boost future 6G systems from both communication and computing perspectives. For example, secure quantum communications such as quantum key distribution can be leveraged to improve 6G security. This article aims to provide a technology-driven and visionary description and exploration on how QIT can be leveraged for future 6G wireless networks.

支持量子的 6G 无线网络：机遇与挑战

随着 5G 商用部署数量的不断增加，超 5G（B5G）和 6G 的研究也已如火如荼地展开。尽管现在明确确定 6G 系统的外观或设计方式还为时过早，但可以肯定的是，6G 系统将支持具有挑战性的关键性能指标 (KPI) 的新用例，这将由新的使能技术和网络架构。近年来，随着蜂窝系统从 5G 向 6G 演进，量子信息技术 (QIT) 在量子通信和量子计算方面发展迅速。预计 QIT 将从通信和计算的角度支持和推动未来的 6G 系统。例如，可以利用量子密钥分发等安全量子通信来提高 6G 安全性。
