KT to expand national quantum communications infrastructure with nationwide testbed

KT plans to expand its quantum cryptography communications testbed nationwide by 2028 and verify next-generation quantum communications technologies based on wireless and satellite links. KT said on Oct. 22 it will push ahead with a project led by the Ministry of Science and ICT and the National Information Society Agency. The project expands the existing testbed centered on Seoul, Pangyo and Daejeon and supports verification and industrialization of next-generation quantum technology.

MSIT to expand quantum communications testbed to support commercialisation and overseas expansion

South Korea will expand its quantum communications demonstration base to support commercialisation and overseas expansion of domestic technology. The Ministry of Science and ICT said it held a kickoff briefing on the open quantum testbed upgrade and expansion project with the National Information Society Agency. The project will add three hubs for commercial, overseas and future uses from 2026 to 2028, with 7.4 billion won to be invested this year.

Google quantum chip Willow cuts computation errors 40-fold, but bitcoin security threat still distant

Google succeeds in cutting errors in “magic state,” a key resource for quantum computing, to about one-fortieth of the previous level. Its Quantum AI team reports achieving 99.99% logical accuracy using its Willow processor, but the performance remains far from levels needed to crack bitcoin or RSA-2048 encryption. Researchers cite a wide gap in required accuracy and note that Willow has 105 physical qubits, far below estimates for such attacks.
