Google Quantum flags crypto risk

Quantum research produced two signals with direct security implications. U.S. researchers reported a breakthrough in open-air quantum data transmission, a step toward secure communications without fixed fiber links. Separately, new estimates from Google Quantum AI suggest a quantum attack on Bitcoin could be closer than previously thought, raising urgency around post-quantum migration. The link is straightforward: the same physics that may enable tamper-evident networking also threatens today’s public-key cryptography. For cloud providers, chip makers, exchanges and standards bodies, the clock is moving from theoretical planning toward engineering roadmaps and budget decisions.
