Concerns are resurfacing that quantum computers could break bitcoin\'s cryptographic system, but an analysis says it is hard to view that as a realistic threat at current technology levels. It says there is little basis to expect a cryptographically meaningful quantum computer within the next 10 years, and it remains uncertain whether such equipment can be developed. The analysis adds that bitcoin should still continue research into post-quantum cryptography.

French photonic quantum computing company Quandela said it will focus over the next two years on finding strategic partners in South Korea and pursuing joint development. It plans cooperation in photonic quantum hardware manufacturing, cryogenic control and system integration, and quantum system operations based on AI, GPUs and high-performance computing. Quandela also unveiled a mid- to long-term roadmap for fault-tolerant quantum computing and proposed a quantum manufacturing consortium involving Korean companies and research institutes.
