kvantvõtmi
Kvantvõtmi, often translated as quantum key distribution (QKD), is a method of secure communication that uses quantum mechanics to generate and distribute cryptographic keys. Unlike traditional cryptography, which relies on mathematical complexity to secure information, QKD leverages the fundamental laws of physics to ensure that any attempt to eavesdrop on the key exchange will be detected.
The most common QKD protocols, such as BB84, involve sending photons, the particles of light, encoded with
A key principle of QKD is the no-cloning theorem, which states that it is impossible to create
Once the secure key is established through QKD, it can be used for symmetric encryption, a method
