Researchers from Caltech and Oratomic, a Caltech-linked startup, published findings on March 31, 2026, arguing that a useful quantum computer capable of running Shor’s algorithm on real cryptographic ...

Future quantum computers will need to be less powerful than we thought to threaten the security of encrypted messages.

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require ...
