KT, a leading telecommunications company in South Korea, has set a goal to expand the range of wireless quantum-encrypted communications from the current 2 km to 10 km by next year. This technological breakthrough could significantly reduce potential hacking threats for future urban air mobility vehicles and military drones.
Wireless quantum encrypted communication technology is considered one of the most recognized technologies in the global defense and security field. With the advent of quantum computers, which have much faster processing speeds than supercomputers, current standard encryption systems may become obsolete.
As quantum computers become commercialized, the risk of hacking existing Internet networks and communications infrastructure increases. This poses a threat to unmanned reconnaissance drones and the security of personal information.
However, quantum encrypted communication, which uses quantum states to pass encryption keys, is virtually unbreakable. Major countries such as USA, China, Germany and Austria are investing in the development of this technology.
KT is a leading company in South Korea, being the first telecommunications company to aggressively develop wireless quantum encrypted communication technology. Unlike wired communication, wireless quantum encryption can provide secure networks in places where optical cable is difficult to install, such as islands or aircraft.
KT has been working on this technology since 2021 and has recently succeeded in extending the quantum signal transmission range to 2 km. Factors such as wind and atmospheric conditions become more important as the transmission distance increases, and precision between the transmitting and receiving devices is required.
To demonstrate its technology, KT has set up a wireless quantum-encrypted communication infrastructure on the Jeju International University campus that spans 300m. This infrastructure will be used for research, development and education until 2025.
In summary, KT aims to extend the range of wireless quantum encrypted communication to 10 km, providing improved security for future aircraft and military drones. This technology is considered virtually unhackable and is being developed by major countries around the world.
