The prospect of quantum computers reaching a practical level within the next decade is drawing renewed attention, as progress emerges in error correction and logical qubit implementation. The focus is shifting to how effectively logical errors can be controlled as physical qubit counts rise. Techniques such as qLDPC codes and Google tests are cited, while AI is also being used in circuit design and qubit layout. The discussion is also reviving concerns about long-term threats to Bitcoin’s cryptography.

South Korea will loosen advertising rules for broadcasters, raising the daily ad cap per channel and easing limits on mid-roll, virtual and indirect advertising. The Broadcasting Media Communication Commission approved a revision to the Enforcement Decree of the Broadcasting Act that will take effect in October after remaining procedures. The agency estimates easing mid-roll ad rules could lift broadcast ad revenue by about 50 billion won. Prime-time limits will remain to curb ad concentration.
