Google pushes for urgent post-quantum upgrades by 2029, citing rapid progress in quantum computing and potential risks to encryption.
Google has set a 2029 deadline for fully migrating to post-quantum cryptography, as stated in their announcement on Wednesday. The company warned that rapid advancements in quantum computing hardware and error correction could soon threaten existing encryption standards.
Google emphasized that quantum computers pose a significant risk to current cryptographic methods, including encryption and digital signatures. They urged other organizations to accelerate their post-quantum efforts to ensure secure authentication services.
Google's Quantum Developments
Google is developing the Willow quantum processor, which has a capacity of 105 qubits, making it one of the most powerful superconducting quantum processors available. This progress underscores the need for timely migration to protect users.
The Ethereum Foundation launched a Post-Quantum Ethereum resource hub on Tuesday, planning to implement quantum-resistant solutions at the protocol level by 2029. This aims to safeguard the billions of dollars in value on the Ethereum network.
Solana developers introduced a quantum-resistant vault in January 2025, using a hash-based signature system that generates new keys per transaction. Users must store funds in these vaults for protection, as it is not a network-wide upgrade.
In the Bitcoin ecosystem, opinions differ on quantum risks. Blockstream CEO Adam Back stated that threats are overstated and no immediate action is needed, while a proposal for a new output type via Bitcoin Improvement Proposal 360 could take seven years to implement, according to security researcher Ethan Heilman.
Cointelegraph reported these developments based on industry statements, highlighting ongoing efforts across crypto networks to address potential quantum vulnerabilities.
