For the first time, a team of physicists in Austria has carried out an experiment that appears to verify the principle of ...

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

Quantum key distribution (QKD) exploits the intrinsic properties of quantum mechanics to enable the secure exchange of cryptographic keys between distant parties. By utilising quantum states of light, ...

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, ...

Scientists have turned simple glass into a powerful quantum communication device that could safeguard data against future quantum attacks. The chip combines stability, speed, and versatility—handling ...

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.

As part of the QuNET project, researchers have demonstrated how quantum key distribution works reliably via hybrid and mobile channels. The results are milestones for sovereign, quantum-secured ...

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

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 ...

In the race to secure digital infrastructure against the looming threat of quantum computing, space has emerged as an indispensable theater. Satellites, once primarily vehicles for reconnaissance and ...
