“…Security and resilience are vital for a smooth process of such delicate operations. 6G with quantum communication can secure this communication by exchanging unbreakable keys between two parties using quantum entanglement [13], [14]. The vulnerability against denial-of-service (DOS) attacks of quantum key distribution (QKD) is described in [15].…”

The first release of 5G technology is being rolled out worldwide. In parallel, 3GPP is constantly adding new features to upcoming releases covering well-known use cases. This raises the questions i.) when will 6G be introduced?, ii.) how can 6G be motivated for the stakeholders, and iii.) what are the 6G use cases? In this work, we present the perspective of these stakeholders, namely the network operators, manufacturers, and verticals, identifying potential 5G shortcomings and the remaining 6G solution space. We will highlight the Metaverse as the enabler for 6G addressing omnipresent daily challenges and the upcoming energy problem.

“…A number of SemCom techniques inspired by the advancements in 6G research [26], [70]; AI [71]- [73], machine learning (ML) [74]- [76], and deep learning (DL) [77]- [79] research; research on quantum computation [63], [80], [81], quantum communication [82]- [84], and quantum networking [62], [85], [86]; and research on optical communications have been proposed in not only the wireless domain -hereinafter referred to wireless SemCom -but also in the optical and quantum domains. These latter domains' respective SemCom paradigms are henceforth referred to as optical SemCom and quantum SemCom.…”

Making Sense of Meaning: A Survey on Metrics for Semantic and Goal-Oriented Communication

2023

View full text Add to dashboard Cite

Semantic communication (SemCom) aims to convey the meaning behind a transmitted message by transmitting only semantically-relevant information. This semantic-centric design helps to minimize power usage, bandwidth consumption, and transmission delay. SemCom and goal-oriented SemCom (or effectiveness-level SemCom) are therefore promising enablers of 6G and developing rapidly. Despite the surge in their swift development, the design, analysis, optimization, and realization of robust and intelligent SemCom as well as goal-oriented SemCom are fraught with many fundamental challenges. One of the challenges is that the lack of unified/universal metrics of SemCom and goal-oriented SemCom can stifle research progress on their respective algorithmic, theoretical, and implementation frontiers. Consequently, this survey paper documents the existing metrics -scattered in many references -of wireless SemCom, optical SemCom, quantum SemCom, and goal-oriented wireless SemCom. By doing so, this paper aims to inspire the design, analysis, and optimization of a wide variety of SemCom and goal-oriented SemCom systems. This article also stimulates the development of unified/universal performance assessment metrics of SemCom and goal-oriented SemCom, as the existing metrics are purely statistical and hardly applicable to reasoning-type tasks that constitute the heart of 6G and beyond.

“…It is expected that, quantum technology will provide resilience by design, device independent security, oblivious transfer and bit commitment [3], making it a worthy extension of 6G. In the first realisation of quantum communication networks, the quantum technologies are expected to be integrated in the existing classical architecture of future 6G networks in order to create a hybrid classical-quantum communication infrastructure [4]. Several large research activities have been started recently to investigate the potential of quantum communication for the application in classical communication networks [5].…”

“…Nevertheless, the quantum channel is not ideal and various kinds of errors may occur, changing not only the 'value' of a so-called qubit but also modifying its 'phase'. Quantum error correction (QEC) codes have been studied to permit the correction of these errors [4]. The work in [8] were pivotal for understanding QEC schemes -particularly, surface codes.…”
