Google just issued a warning that has great implications for the cybersecurity world: "Q-Day" — the moment when a quantum computer becomes powerful enough ...
For much of the past decade, post-quantum cryptography (PQC) lived primarily in academic journals and standards committees.
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 ...
Most business leaders don’t think about cryptography—and that has always been the point. For decades, encryption quietly protected data in the background, rarely demanding attention once systems were ...
Sending secret messages to your friends is fun, but today it’s so simple that you don’t even notice it anymore: practically any serious messaging system features encryption of some sort. To teach his ...
Real, but not immediate Ethereum relies on cryptographic systems that remain secure against classical computers. However, ...
No longer relegated to post-doctorate physics academia and sad Schrödinger's cat thought experiments, post-quantum computing remediation has arrived in the real world. Quantum computing is expected to ...
In 1994, the computer scientist Peter Shor discovered that if quantum computers were ever invented, they would decimate much of the infrastructure used to protect information shared online. That ...
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 ...
