Building on a landmark algorithm, researchers propose a way to make a smaller and more noise-tolerant quantum factoring circuit for cryptography. The most recent email you sent was likely encrypted ...

Quantum information science is now a fast-growing field, but when 2025 ACM A.M. Turing Award recipients Charles H. Bennett ...

By the time Bitcoin and other networks are ready to defend themselves, it may already be too late, according to a new ...

Quantum computing represents a looming—and inevitable—threat to almost every aspect of our digital world that is protected by current forms of encryption. Either within this decade or the next, ...

The FIDO2 industry standard adopted five years ago provides the most secure known way to log in to websites because it doesn’t rely on passwords and has the most secure form of built-in two-factor ...

Michael Shaulov argued that changing to a post-quantum cryptographic signature scheme is “not a technical challenge” for ...
