Both the words 'Quantum Key Distribution' and 'Quantum Key Exchange' are used in quantum cryptography in the problem of a secure key distribution for encryption/decryption between parties. There are popular algorithms like the BB84, B94 and E91 protocols for the above-stated task.

However what I want to know is that is there a difference between the two terms 'Quantum Key Distribution (QKD)' and 'Quantum Key Exchange (QKE)' or both represent the same concept?
