What is quantum key distribution?
Quantum key distribution (QKD) is a method of secure communication that uses quantum mechanics to share encryption keys.
How does it ensure security?
QKD ensures security by detecting eavesdroppers; any attempt to intercept the key changes its state, alerting the parties.
Can you explain the process in simple terms?
Sure! QKD involves sending quantum bits (qubits) between two parties. If someone tries to listen in, the qubits change, revealing the breach.
What are its real-world applications?
QKD is used in secure communications for banks, government agencies, and even in satellite communications to protect sensitive data.
