The first quantum key distribution (QKD) protocol, BB84, was introduced by American physicist Charles H. Bennett and Canadian cryptographer Gilles Brassard 1 in 1984. Over the past four decades, QKD ...
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 ...
Most quantum key distribution schemes exploiting orbital angular momentum-carrying optical beams are based on conventional set-ups, opening up the possibility of detector side-channel attacks. These ...
