Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require nearly the resources anticipated just a year or two ago, two independently written whitepapers have concluded.

New research involving Google has outlined how quantum computers could one day break the cryptographic systems underpinning major blockchains. It reinforces recent efforts by Ethereum Foundation to prepare for a post-quantum future.

Google’s new research potentially puts the entire bitcoin supply – and the very foundation of digital trust – at risk, explains Pruden.

By Laurie Chen BEIJING, March 19 (Reuters) - China will likely develop national standards for post-quantum cryptography in the next three years as it pours funds into research, according to a leading expert in the field.

"Our collaboration with ZeroRISC on post-quantum cryptography demonstrates exactly what becomes possible when you do. Open-source silicon accelerates research the same way open-source software always has, and produces cryptographic implementations that meet the highest standards of performance, security, and long-term maintainability.
