Over a decade ago, when I was first starting to pretend I could write about quantum mechanics, I covered a truly bizarre ...

A new quantum communication method uses the temporal Talbot effect to simplify high-dimensional quantum key distribution.

A quantum internet is only as useful as its reach, and in a first, researchers created more than a million qubit pairs across 100 kilometers of fiber.

Korean researchers have successfully established a measurement protection (MP) theory that enables stable quantum key distribution (QKD) without the need for measurement correction of quantum states, ...

Continuous-variable quantum cryptography has emerged as a significant branch of quantum cryptography, with continuous-variable quantum key distribution (CVQKD) at its core. However, compared to ...

A new technical paper titled “A Practical Implementation of Quantum-Derived Keys for Secure Vehicle-to-Infrastructure Communications” was published by University of Warwick. “We provide a practical ...
