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 ...

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 ...

Even though large scale quantum computing are years away from being a practical reality, federal government experts are rightfully worried about the cryptography implications today. The threat is ...
