Galaxy Digital launches research and advisory board to address Bitcoin quantum threat

Crypto investment firm Galaxy Digital has started a programme to prepare for potential quantum-computing threats to Bitcoin, committing up to $5 million. The initiative bundles developer grants, research and a new advisory board aimed at speeding network upgrade readiness. It will fund work such as quantum-resistant transaction proposals, post-quantum signature integration, wallet and custodian migration tools and formal code security audits. Galaxy says the risk is a long-term technical challenge.

PsiQuantum presses ahead with photon-based large-scale quantum computer

Quantum computing company PsiQuantum is accelerating efforts to build a large-scale quantum computer using photons. It is pursuing an approach that makes chips in existing semiconductor production facilities and connects about 100 cooling cabinets to implement a practical-scale system. Founded in 2016 by four physicists from British universities, the company has raised $1 billion and begun work on a Chicago hub, while preparing a second hub in Australia.

Perplexity cuts reasoning costs with Chinese open-source model, claims Claude Opus-level performance at one-third the cost

Perplexity released a research preview of a model it post-trained from Chinese open-source AI model GLM 5.2 for its agent system. It said the model delivers performance comparable to Anthropic\'s Claude Opus 4.8 at about one-third of the cost, routing most tasks to GLM 5.2 and sending only difficult ones to Opus 4.8. The company said the approach reduced costs versus using Opus for all tasks.
