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, ...

Quantum key distribution (QKD) is an emerging communication technology that utilizes quantum mechanics principles to ensure highly secure communication between two parties. It enables the sender and ...

Quantum communication could enable uncrackable transfer of information, but most approaches rely on trusted devices. Researchers have now demonstrated that a new method that does away with this ...
