Quantum cryptography? Pah! That's for newbies, according to researchers from Texas A&M University who claim to have pioneered unbreakable cryptography based on the laws of thermodynamics; classical ...

Unlike classical encryption, quantum communication systems are known to offer the promise of virtually unbreakable encryption. Now, new research on this topic is shaking up the long-held notion that ...

Current public-key cryptography is expected to be broken by a large-scale quantum computer as soon as eight years from now. There is no question that quantum computing poses significant risks to the ...

The original version of this story appeared in Quanta Magazine. Say you want to send a private message, cast a secret vote, or sign a document securely. If you do any of these tasks on a computer, you ...

Over on YouTube, [The Modern Rogue] created an interesting video showing a slide-rule-like encryption device called the Réglette. This was a hardware implementation of a Vigenère-like Cipher, ...

New documents leaked by Edward Snowden reveal two NSA programs that seek to build a "useful quantum computer" that can break all known forms of classical encryption. Such a quantum computer would ...

Forbes contributors publish independent expert analyses and insights. Paul-Smith Goodson is an analyst covering quantum computing and AI. Last year I wrote a Forbes article that provided a deep dive ...

Chinese researchers at Shanghai University say they’ve inched towards cracking military-grade encryption — with the help of a quantum computer. SPNs are used in algorithms tasked with protecting ...
