Quantum Security for the Tactile Internet

The Tactile Internet aims at enabling the transmission not only of audiovisual but also of tactile information. However, the combination of audiovisual and haptic signals for families of use cases like human-machine cohabitation and remote control of robots requires very stringent requirements in terms of latency, reliability, and security. That is why, the previous research on 5G and the current one on 6G are trying to design communication networks with the necessary technological characteristics. Nevertheless, ’classical’ technologies are showing more and more their intrinsic limitations to satisfy the required Key Performance Indicators when paradigms like full network softwarization, in-network intelligence and computing, and big data mining become part of the network design. Then, the interest for inherently different and new technologies/resources like quantum-mechanical have been rising. However, the maturity of these technologies for direct implementation in future 6G networks and the Tactile Internet is still to be achieved. The objective of this chapter is to explain the main characteristics of quantum technologies and paradigms that could be applied to enable efficiently and effectively the Tactile Internet. ... mehrSome critical considerations are mentioned in order to highlight the main pros and cons of each solution.
