1、ACHIEVING QUANTUM-READINESS IN 5G NETWORKS:WHAT OPERATORS NEED TO KNOWQuantum State of Play in 5GQuantum mechanics has come a long way since the discovery of the initial fundamentals in the early nineteenth century.The field of quantum computing has since emerged from the physics,finding theoretical

2、 application in modern computation systems including within cellular networks such as 5G.Although security and privacy were seriously considered during the 5G standardization process,quantum computers could seriously undermine the confidentiality and integrity of the most modern telecommunications n

3、etworks,including 5G.5G is opening up a whole new set of opportunities for connectivity.However,privacy and data security concerns are set to play a key role as new vendors and new technologies emerge to capitalize on 5G capabilities.This expansion,added to the significant architectural changes,and

4、quantum in particular,will make for highly complex networks,exposing new vulnerabilities and greater risks as we move towards a Post Quantum Crypto world.While todays market opportunity for 5G security currently lies in network security solutions targeted at telco operators,increasingly,this will be

5、 overshadowed by demand for software and service security,with the market expected to reach US$8.6 billion(7.96 billion)in revenues by 2027;a growing share of that will come from enterprise markets who will look to secure specific applications(e.g.,URLLC,MMTC)and configurations(e.g.,network slices),

6、and to prepare their networks for PQC.Research in quantum computing is closely tied to the discipline of information theory,a mathematical concept concerned with communication,coding,and encryption,pioneered by the likes of Turing,von Neumann,and Shannon in the mid-twentieth century.Various CONTENTS
