Quantum computers will fundamentally change the way we look at humanity’s most complex problems. They promise new insights, from materials science to medicine and climate research. However, this ...

With growing focus on the existential threat quantum computing poses to some of the most crucial and widely used forms of encryption, cryptography engineer Filippo Valsorda wants to make one thing ...

What’s the best way to solve hard problems? That’s the question at the heart of a subfield of computer science called computational complexity theory. It’s a hard question to answer, but flip it ...

Two researchers have improved a well-known technique for lattice basis reduction, opening up new avenues for practical experiments in cryptography and mathematics. In our increasingly digital lives, ...

The original version of this story appeared in Quanta Magazine. Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the ...

Companies are aware of the risks posed by quantum computers and are making an inventory of all the areas where they use ...

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 ...

Every time you log into your bank, send an email, or connect to a VPN, encryption quietly does the heavy lifting. The internet feels simple. The security underneath it? Anything but simplicity. That’s ...

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 ...
