... one day make data encryption that is "hack-proof" is quantum key distribution (QKD). QKD uses individual light quanta (single photons) and relies on one of the fundamental aspects of quantum mechanics to make the encryption safe. Put very basically...
... quantum key distribution (QKD) come into the picture. Unlike classical cryptography, quantum key distribution either uses the inherent uncertainty in the states of quantum particles like photons or quantum entanglement to securely set a quantum key...
