This decade has seen an explosion of exploration into softwarisation and virtualization of network functions and services for 6G communication networks and beyond. The concept of service function chaining (SFC) is becoming increasingly integral to proposed solutions that are able to fulfill network requests and services while adhering to the sophisticated key performance indicators (KPIs) of 6G communications and the tactile internet. But new technologies are needed to achieve the set-out cutting-edge requirements and next-generation numbers for low latency, energy efficiency, etc. without suffering from the traditional trade-offs observed when using existing classical technology. Quantum technology is a promising candidate to achieve this, given how it utilizes unique quantum mechanical phenomena like quantum entanglement and quantum interference to resolve problems in a manner often simply non-existent from a classical standpoint. In this paper, we explore utilization of quantum entanglement technology for a specific network scenario involving chains of virtualized network functions (VNFs) that together offer equivalent network functionality, and we discuss some potential advantages of using quantum networks that make use of quantum entanglement over classical technology networks.

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.
There is a great attention to quantum technologies in the ICT environment. In particular, when dealing with security matters, the most prominent quantum technology is Quantum Key Distribution (QKD). QKD allows the sharing of symmetric keys with information theoretic security (ITS, i.e. independently of the computational power of the attacker) between two remote network nodes. QKD is the only known method to share a key able to reach ITS. During the last two decades, there has been a tremendous technological progress in QKD research, that has led to the availability of QKD network demonstrators.Software Defined Networks (SDN) enables the automation of service provisioning within network operator infrastructures. With the advent of web-scale services and dynamic network requirements, operators can not anymore deploy their services based on manual intervention or using proprietary vendor solutions. Programmability is key in the next-generation network infrastructure and any new technology must be integrated with this paradigm. Let us highlight that this requirement is even more important with virtual environments, where a Virtual Network Function (VNF) can be deployed in any point-of-presence of the operator. The new 5G deployments will enable operators to have edge computing services supporting different capabilities, thus increasing even more the complexity to deliver services without any automation.In spite of the high potential of QKD, this technology has not yet found its path to wide adoption, commercialization and deployment. QKD is a physical technology that requires the existence of a quantum channel, a physical connection able to transmit quantum bits without perturbation, making hard its integration in networks. The aim of this document is to present how QKD can be deployed in next generation infrastructures, based on realistic scenarios. To do so, this paper describes the technological components of the solutions, as well as the use cases that motivate such effort. These use cases are described from a telecommunication provider's point of view, as they are the actors in charge of deploying QKD systems in their networks.
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 computing is a technology that utilizes quantum mechanics principles such as superposition and entanglement to offer significant advantages over classical computing.With the development of sixth generation (6G) technology quantum computing's high data processing capacity, efficiency in optimization processes, and contribution to secure communication systems are becoming increasingly important.This paper examines the role of quantum computing in 6G networks.It discusses its potential contributions in areas such as network optimization, quantum machine learning, secure communication protocols, and fault-tolerant computing.The ultra-low latency, high data rate, and dynamic spectrum management requirements of 6G can be significantly improved by integrating quantum algorithms and hybrid quantum-classical systems.However, obstacles such as current limitations in quantum hardware, error correction requirements, and implementation challenges are also considered in detail.The paper outlines the potential solutions that quantum computing can provide to meet the performance demands of 6G, and discusses future research directions to further explore this promising technology intersection.
The quantum internet is a candidate network technology for specific future xURLLC communication scenarios that will entail sending, receiving, storing and manipulating information encoded in quantum states in order to provide new services such as quantum cloud computing and real-time materials science simulations. Efforts concerning the creation of the quantum internet are predicated conceptually on quantum mechanics, and involve the transmission of qubits - bits of quantum information -across different physical platforms (trapped-ion systems, superconducting circuits, etc.) while leveraging physical phenomena like quantum entanglement and quantum superposition to offer properties like increased security and decreased latency in some contexts of communication. In this paper, we briefly review the state-of-the-art of quantum networks based on different physical platforms, and investigate as to how they may play a key role in offering unprecedented and/or unique advantages in the realm of 6G communication networks and beyond.
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.
