Google has set 2029 as its target to roll out post-quantum cryptography across its products, adding a firm deadline to a risk that has moved closer in recent years.\u00a0<\/strong><\/p>\n <\/p>\n The company linked that timeline to faster gains in quantum hardware, better error correction, and new estimates on how quickly current encryption could become vulnerable.<\/p>\n Google said the industry should move sooner rather than later as quantum computing advances continue. The company stated that current cryptographic standards used for encryption and digital signatures will not remain safe forever.<\/p>\n <\/p>\n In its update, Google said<\/a>,\u00a0<\/p>\n \u201dQuantum computers will pose a threat to current cryptographic standards.\u201d\u00a0<\/p>\n<\/blockquote>\n It also said post-quantum migration is needed so users can continue to rely on secure authentication services across its products.<\/p>\n The 2029 timeline marks the first time Google has attached a clear migration target to its post-quantum work. That date arrives earlier than some estimates<\/a> for Q-Day, the point when quantum machines could break widely used public-key encryption.<\/p>\n Google said it wants to set a public example for other companies and institutions. The company added, \u201dIt\u2019s our responsibility to lead by example and share an ambitious timeline,\u201d while calling for wider action across the industry.<\/p>\n Moreover, the push toward quantum-safe systems is also gaining attention in crypto. The Ethereum Foundation launched a Post-Quantum Ethereum resource hub this week and said it wants protocol-level protections in place by 2029.<\/p>\n Ethereum\u2019s plan focuses on securing the network against future quantum threats, with execution-layer work expected later. The effort reflects broader concern over how blockchains that rely on existing cryptographic systems may need upgrades over time.<\/p>\n Solana developers introduced a quantum-resistant vault in January 2025. The design uses hash-based signatures and creates a new key during each transaction, but users must move funds into special Winternitz vaults because the feature does not upgrade the full network.<\/p>\n\n
