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, ...

IonQ deployed what it claims to be the largest and most complex quantum key distribution (QKD) network in Europe. The initiative came out of a project with Romanian institutions, including the ...

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

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

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 ...

The rise of quantum computing poses both promise and peril for modern cryptography—and blockchains lie right at the crossroads. As machines become capable of shattering our current cryptographic ...
