Evolution towards 6G communication networks aims to support burgeoning alternative technologies in order to overcome traditional classical trade-offs in various aspects of network performance, security, and latency. With this pursuit also striving to meet more nuanced aspects of purported trustwor-thiness standards, the soaring complexity of the next-generation networks is unsurprising; additional classical resources (third-party random number generators, pre-shared keys, etc.) are thus becoming increasingly relied upon for optimal network functioning. In this paper, we explore the potential of quantum technology and how it might be possible to utilize quantum phenomena like quantum entanglement to transfer decisional information in specific network contexts while also inherently providing destination anonymity without requiring additional classical resources.

As the world outgrows the capabilities of 5G networks, the search for the next technical standard — 6G — accelerates, promising unprecedented connectivity, capability, and adaptability. However, optimizing network performance to simultaneously satisfy purported multiple key performance indicators — latency, energy efficiency, resilience, trustworthiness etc. — is a herculean struggle. Traditional Shannon-based communication models struggle to address and overcome the complex tradeoffs required in ultra-reliable, low-latency, and secure network architectures. It is no surprise, then, that emerging paradigms such as semantic communication, goal-oriented communication, and quantum communication are being integrated into telecommunication research. Unlike classical communication, semantic communication focuses on transmitting meaning more so than merely raw data; additionally, quantum semantic communication leverages quantum mechanics to further optimize information processing and security. In this paper, we conceptually investigate whether these theoretical technological advancements, when interpreted in the right context, can intrinsically enhance resilience in 6G networks.
5G is the new generation of mobile communication that is taking over the 3G and 4G generations. As our generation has expanded and continues to work faster and more adapt to the electronics of today, we are faced with the ever-improving technologies to keep us moving forward. 5G has the possibility of faster upload and download speeds. The possibility of more and improved smart products to advance our lives, from autonomous cars, smart traffic lights, improved city Wi-Fi availability, and gaming improvements with no lag time, just to name a few. It is expected that 5G/6G will make it wide open for new frequency ranges which will result in many connections and huge data transfer maintaining high network efficiency. With 6G on the horizon, Quantum Computing and networking are playing a key role. We anticipate that Quantum Information Technologies will enable and support future 6G systems in both communication and computing. Quantum computing networks boast a few potential security and performance advantages compared to incumbent network technology. The security and energy efficiency of quantum networks is superior to present solutions because quantum networks can theoretically work with single photons whose quantum states remain undisclosed in transmission from origin to destination. Quantum computing networks and associated technology may begin to be implemented in 5G networks and could become fully implemented with the advent of 6G networking technology. In this work, we are focusing on the security risks that can be involved with the new 5G and their proposed solutions. We will study the role of Quantum Key Distribution as leverage to improve 6G security.
In general, quantum technologies and quantum algorithms possess transformative potential for next-generation communication systems. Particularly with the unprecedented data speeds, ultra-low latency, and seamless global connectivity promised by 6G, these technologies are expected to offer significant opportunities for telecommunications and mobile network operators. The integration of quantum computing can play a role in optimizing network operations, improving resource management, reducing energy consumption, and increasing data processing efficiency. For mobile network operators, this will result in significant progress in key performance indicators (KPIs) such as scalability, reliability, and security. Furthermore, quantum cryptography will be of critical importance by introducing new security standards for real-time data protection. This paper will focus on a mobile network operator�s perspective and explore potential solutions. It will assess the synergy between quantum technologies and telecommunications, focusing on key topics such as network latency, bandwidth optimization, and energy efficiency. By leveraging quantum computing, the paper will explore how future telecommunications networks can become faster, more secure, and more sustainable.
Quantum technologies hold promise as essential components for the upcoming deployment of the future 6G network. In this future network, the security and trustworthiness requirements are not considered fulfilled with the current state of the quantum computers, as the malicious behaviour on the part of the service provider towards the user may still be present. Therefore, this article provides an initial interdisciplinary work of regulations and solutions in the scope of trustworthy quantum computing for future 6G that can be viewed as complimentary regulations to the existing strategies shared by different actors of states and organizations. More precisely, we describe the importance of a reliable quantum service provider and its implication on the ethical aspects concerning digital sovereignty. By exploring the critical relationship between trustworthiness and digital sovereignty in the context of future 6G networks, we analyse a trade-off between accessibility to this new technology and preservation of digital sovereignty engaging in parallel the United Nation's (UN's) sustainable development goals. Furthermore, we propose a partnership model based on cooperation, coordination, and collaboration giving rise to a trusted, ethical, and inclusive quantum ecosystem, whose implications can spill over to the entire global scenario.
Abstract Over the past four decades, quantum communication has evolved as a dynamic interdisciplinary field, advancing theoretical concepts and practical implementations. This article provides a concise overview focusing on recent progress in different aspects of secure quantum communication and quantum computation protocols, which can be applied to several real-world applications in quantum networks. These protocols guarantee unconditional security while enhancing communication rates and computation capabilities by harnessing quantum advantages. We also explore the role of non-terrestrial networks in quantum applications, with a focus on quantum technologies such as quantum key distribution and beyond, suitable for satellite-based applications. These technologies can contribute to future extensions of the quantum internet across intercontinental territories, connecting complex quantum network applications. Further, we delve into discussing the integration of quantum communication into 6G technology. The key innovation of this article lies in integrating quantum communication into 6G networks through a novel system-level simulation framework. 6G-enabled quantum networks are expected to meet the high demands on ubiquitous coverage, data rate, latency, and energy consumption. To address these issues, we design and evaluate four traffic demand scenarios using numerical simulation, illustrating how superdense coding doubles the data transmission rate and fulfills the high traffic demands on data rate, while under low traffic demand, entanglement resources can be reserved for future applications. Specifically, our investigation demonstrates how resource utilization adapts to different traffic demands, with adjustments based on available resources and practical constraints, evaluated over an ideal noise-free communication channel. The proof-of-work simulation is implemented using Python and is based on the system model we designed for varying traffic demands to pave the way for efficient quantum networks and gain deeper insights into their feasibility with available resources.
Network Function Virtualization (NFV) has enabled scalable deployment of novel user service requests in current and future communication networks (sixth generation (6G)). However, virtualization also introduces down functioning of certain Key Performance Indicator (KPI)s such as latency. Novel technology like quantum computing has potential to surpass these limitations. One of the problems to tackle in NFV based systems, is decision making for Virtual Network Function (VNF) migration. Classical and quantum solutions are proposed for this problem. It is observed that both solutions ensure anonymity; however lesser overhead is required in the quantum solution. Further, future research directions are discussed as well to inculcate quantum technology into broader class of problems in 6G communication networks.
