A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending ...

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, ...

While the basic form of QKD enables information to be transmitted securely, it does have some weak points. One of them is ...

A research team has developed the world's first quantum microsatellite and demonstrated real-time quantum key distribution (QKD) between the satellite and multiple compact, mobile ground stations. The ...

TIM is testing the first quantum-safe connection between two data centers on an operational network in Milan: Qkd on 40 km of fiber with active traffic, focus on digital sovereignty and EuroQCI ...

Germany has taken a significant step toward secure digital communication. Researchers under the QuNET research program have shown that quantum key distribution (QKD) can work reliably across hybrid ...

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 ...

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 ...
