Google to Make Quantum Migration by 2029

Google has set a 2029 deadline for its post-quantum cryptography (PQC) migration, warning that “quantum frontiers” could be closer than they appear.

On Wednesday, Google said rapid progress in quantum computing hardware and quantum error correction, along with updated estimates of how quickly a quantum machine could break today’s encryption standards, has heightened the urgency to act sooner rather than later.

“Quantum computers will pose a significant threat to current cryptographic standards, and specifically to encryption and digital signatures,” Google said, while also noting that PQC migration is needed for users to use authentication services securely.

This is the first time Google has set a timeline to roll out post-quantum capabilities across its products. The 2029 timeline is earlier than some industry estimates for Q-Day — the point at which quantum computers become powerful enough to break current public-key encryption.

“It’s our responsibility to lead by example and share an ambitious timeline. By doing this, we hope to provide the clarity and urgency needed to accelerate digital transitions not only for Google, but also across the industry.”

Google’s call for urgency comes as it continues to develop its quantum chip, Willow, which has a computing capacity of 105 qubits, making it one of the most powerful in the industry.

There are also rising concerns that quantum computers could severely disrupt the crypto industry by breaking the cryptographic algorithms used to secure digital assets. However, there is still debate over whether only crypto wallets with exposed public keys are vulnerable or whether all coins are at risk.

Crypto networks also eye post-quantum upgrades

The Ethereum Foundation launched a “Post-Quantum Ethereum” resource hub on Tuesday, focused on protecting the blockchain from future quantum computing threats and securing the billions of dollars in value on the network.

The post-quantum team plans to implement quantum-resistant solutions in Ethereum at the protocol level by 2029, with solutions targeting the execution layer to follow.
