According to foreign media reports, SK Telecom said on Monday that after two years of research, the operator successfully developed quantum relay for the first time in South Korea, making Korea the third to achieve next-generation security after China and the United States Technology country. Quantum cryptography is considered the most secure form of communications encryption that can not be ruined by existing hacking techniques. In its press release, SK Telecom said quantum cryptography is expected to replace all existing security solutions at risk of data theft, including defense, finance, autonomous vehicles and the Internet of Things. Quantum repeaters developed by SK Telecom, known as the "Trusted Repeater," dramatically increase quantum communication's reach and achieve a record 112 km quantum key distribution (QKD) transmission distance. Before developing this quantum repeater, the QKD has a maximum transmission distance of about 80 km due to the use of weak single-photon quantum signals. QKD transmission distance limit is considered to be the biggest obstacle to its commercial. Now SK Telecom hopes to promote commercialization by installing five repeaters and distributing quantum key between Seoul and Pusan ​​at a distance of about 460 km. The company will work with its global partners to not only apply quantum cryptography solutions (including quantum repeaters) to its commercial LTE network in Korea, but also to deploy in overseas commercial networks. "SK Telecom unveiled a new chapter in the development of quantum technology through the development of Trusted Repeater, an enabler of long-range quantum communication," said Park Jin-hyo, senior vice president of network communications and research at SK Telecom. "SK Telecom will continue its commitment to developing key quantum cryptography and building related ecosystems." SK Telecom said the operator will apply its quantum cryptography technology to a commercial LTE network (fiber optic cable network) in Sejong City in 2016 and will collaborate with the Korea Science and Technology Information Institute (KISTI) in May 2017 in South Korea Daejeon Research and Development Center part of the advanced science and technology research network (SuperSiReN) has been applied. SK Telecom quoted consulting firm Market Research Media data said that Korea's quantum cryptography communications services market will usher in explosive growth in 2021, by 2025 will reach 1.4 trillion won. Globally, this area will increase to 26.9 trillion won in 2025. SK Telecom has been actively developing core quantum cryptography since the establishment of the Quantum Technology Lab in 2011. In February 2017, SK Telecom and Nokia reached an agreement to cooperate in quantum cryptography and establish a quantum alliance with Deutsche Telekom aimed at securing communications in the era of quantum computing.
