A team of Google researchers just set a new date for post-quantum cryptography migration: 2029. Among other things, this means that Bitcoin, as well as many other cryptocurrencies, needs to adopt new cryptographic techniques that are resilient to quantum attacks within three years.

Charles Bennett and Gilles Brassard have won the 2026 Turing Award for inventing quantum cryptography. I am incredibly pleased to see them get this recognition. I have always thought the technology to be fantastic,

Google warned that quantum advances could break crypto security sooner than expected, with analysts recommending ‘appropriate urgency.’

The operating assumption must be that AI agents will eventually be granted deep access to our most sensitive systems.

Google researchers warned that future quantum computers may be able to break some of the cryptography protecting Bitcoin and other digital assets with fewer resources than previously thought, adding urgency to the debate over how the industry should prepare.

Sui Research’s new quantum-safe wallet upgrade method offers a hard fork-free solution for EdDSA-based blockchains, but does not apply to Bitcoin or Ethereum.

The original version of this story appeared in Quanta Magazine. In our increasingly digital lives, security depends on cryptography. Send a private message or pay a bill online, and you’re relying on algorithms designed to keep your data secret.

Kimmo Järvinen is a hardware cryptography engineer and researcher with nearly 20 years of experience in the field. He has authored more than 60 scientific publications on cryptography, cryptographic engineering, and secure embedded systems, and holds a PhD in electrical engineering from Helsinki University of Technology.

Quantum computing may one day outperform classical machines in solving certain complex problems, but when and how this “quantum advantage” emerges has remained unclear. Now, researchers from Kyoto University have linked this advantage to cryptographic ...
