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,

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.

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

In a post published on Wednesday, Google said it is giving itself until 2029 to prepare for this event. The post went on to warn that the rest of the world needs to follow suit by adopting PQC—short for post-quantum cryptography—algorithms to augment or replace elliptic curves and RSA, both of which will be broken.

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 ...
