What Does Quantum Key Distribution (QKD) Mean?
Quantum key distribution (QKD) is the use of laser beams to transmit cryptographic keys securely using the quantum properties of photons in laser beams. The photons are coded in binary ones and zeroes which are then picked up by the receiving equipment. This makes it possible to transmit keys without them being intercepted.
Techopedia Explains Quantum Key Distribution (QKD)
Quantum key distribution exploits quantum mechanics to transmit keys between two parties securely. While a key, or a one-time pad, is theoretically unbreakable, the key challenge is getting both parties in a conversation to agree to the same key without the key being intercepted by a third party.
