Quantum computers may reach practical use within 10 years as key bottlenecks ease

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.

Quantum computing threatens bitcoin, VanEck says solution exists even if slow

Bitcoin could be exposed to threats from quantum computing, but its community is already preparing responses, an assessment said. VanEck digital assets research head Matthew Sigel said bitcoin\'s decentralised structure could slow action, but technical solutions are being discussed. Industry concerns focus on whether future quantum computers could break bitcoin\'s cryptography, though none can do so now. Developers are testing quantum-resistant signatures, while Coinbase, Blockstream and a new security consortium are developing and backing proposals.

Kevin O\'Leary sees bitcoin at $1 million, but says quantum computers are a variable

Kevin O\'Leary (케빈 오리어리) said bitcoin could rise to $1 million in the long term, but warned that institutional investors would need concerns addressed that quantum computers could break bitcoin’s cryptography. He also said his strategy has shifted away from focusing mainly on bitcoin and ethereum, and he expects blockchain adoption to diverge by industry. O\'Leary cited SEC regulatory changes around tokenised stocks and said he is investing in power infrastructure for AI, including uranium.
