Quantum Key Distribution (QKD) is a method used to secure communication by allowing two parties to generate and share a secret encryption key using the principles of quantum mechanics. QKD relies on the unique properties of quantum entanglement and superposition, ensuring that any attempt to eavesdrop on the key exchange will be detected. This makes QKD an essential application of entanglement in quantum technologies, paving the way for secure communication channels that are theoretically immune to hacking.
congrats on reading the definition of QKD. now let's actually learn it.
