 Quantum Key Distribution, QKD, is a secure method of distributing cryptographic keys between two parties, even if they are being monitored by a malicious third party. QKD uses quantum mechanics to encode information onto photons, which can then be transmitted over long distances without being intercepted or altered. This allows for secure communication between two parties, even when the third party is actively trying to gain access to the data. QKD has been successfully implemented in real-world settings and is now commercially available. Continuous Variable QKD, CVQKD, which uses continuous variables instead of discrete qubits, offers several advantages over traditional QKD methods, such as simpler implementation and lower cost. CVQKD also provides greater resistance against side-channel attacks, making it more secure than its predecessors. Future developments in CVQKD will likely lead to further improvements in the security of this technology. This article was authored by Eleni Diamanti and Anthony Lebrier.
