The Quantum Threat to Bitcoin Dividing Crypto

Two new research papers—one from Google and another from Caltech researchers at startup Oratomic—have revived a long-running question in crypto. What happens when quantum computing becomes powerful enough to break modern cryptography? Researchers warned this week that advances in the field could threaten the cryptographic systems underpinning cryptocurrencies and other digital infrastructure sooner than expected, showing that future machines may be able to break elliptic curve cryptography with...
