The emergence of quantum computing and its ability to solve computations with incredible speed by harnessing the fundamental properties of quantum mechanics could revolutionize our world. But what ...

Quantum key distribution Researchers at Heriot-Watt University in Edinburgh, UK generated a secure key containing over a million bits and used it to securely share an image between four users in the ...

A team of physicists at the Hebrew University of Jerusalem has made a breakthrough that could bring secure quantum communication closer to everyday use—without needing flawless hardware. A major ...

With the DPS protocol 21, the information-carrying quantum state is defined over many pulses from a coherent laser source. The sender, conventionally called Alice in the field of cryptography, ...

You’d be hard-pressed to find anyone in data security these days who doesn’t start to sweat when they hear the word “ransomware”—malicious software that harvests data in exchange for cash or, in today ...

A claimed first-of-a-kind quantum key distribution network offers 800 Gbps encryption under real-world environmental conditions and has been demonstrated to detect and defend against quantum threats.

From applications in hospitals to automated cash machines, encryption is a crucial and ever-growing part of our digital world. It's what makes information interchange between different organisations ...

The encryption that we rely on to secure network transactions is based on a simple computational challenge: it's hard to find two prime numbers when you're only given the big number that they produce ...
