Quantum Communication: South Korea Expands Testing Network

South Korea is actively developing its national quantum communication test network, initiating an expansion in collaboration with leading telecommunications companies KT and SK Broadband. This ambitious project, planned until 2028, involves extending advanced infrastructure to new regions across the country. An important part of the plan is the integration with experimental sites in Singapore, Poland, and Bulgaria, which will create an international foundation for testing and developing quantum technologies. The key objective of the expansion is to test and refine critical technologies such as quantum key distribution (QKD) and post-quantum cryptography. These areas are of immense importance for ensuring future data security against potential threats from quantum computers. The successful implementation of these solutions could fundamentally change approaches to encryption and information protection. As part of the program, funding of 7.4 billion won has been allocated for 2026. These funds will be directed towards developing hardware, software, and conducting comprehensive tests. The project demonstrates South Korea's commitment to leadership in quantum communications and highlights the importance of international cooperation in accelerating progress. The development of quantum communication represents a significant step forward in information security. While this technology currently has no direct relation to operations like bitcoin exchange or buying BTC with rubles, it could potentially impact the security of all digital transactions in the long term, including those conducted via a crypto exchanger.
