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 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 secure communication uses quantum mechanisms to secure classical (non-quantum) communication and is fundamental to national information security and socioeconomic development. One of 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 ...

A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric ...

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 ...

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, ...

Researchers have brought together two Nobel prize-winning research concepts to advance the field of quantum communication. Scientists can now efficiently produce nearly perfect entangled photon pairs ...
