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, ...

Charles H. Bennett and Gilles Brassard have spent more than four decades proving that the strange behavior of quantum ...

The ability to send quantum information securely, known as quantum key distribution, is one of the most practical (if difficult) applications of quantum science. A new study demonstrates the ...

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 ...
