Quantum computing has long been portrayed as a looming threat to cybersecurity. Headlines warn of “Q-Day”—the moment when quantum machines will render today’s encryption useless. But behind the hype ...

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 ...

Fabric Cryptography, a hardware startup by MIT and Stanford dropouts (and married couple) Michael Gao and Tina Ju, wants to make modern cryptographic techniques like zero-knowledge proof (which lets ...

It’ll still be a while before quantum computers become powerful enough to do anything useful, but it’s increasingly likely that we will see full-scale, error-corrected quantum computers become ...

Cryptography is an obscure discipline. Unless you're in big tech, a university or a research organization, you're unlikely to meet its practitioners. Even then, you might have to search to find them.

“The Willow chip is not capable of breaking modern cryptography,” Google’s director of quantum tells us. “The Willow chip is not capable of breaking modern cryptography,” Google’s director of quantum ...

Cryptography secures digital data using algorithms, essential in private secure communications. Cryptos use cryptographic methods like asymmetric encryption and hash functions for transactions.

The original version of this story appeared in Quanta Magazine. For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You’d scramble the message using a ...

Since ancient times, people have relied on cryptography, the art of writing and solving coded messages, to keep their secrets secure. In the fifth century, enciphered messages were inscribed on ...
