Quantum Cryptography: Physics That Cannot Be Hacked

Quantum cryptography uses the principles of quantum mechanics to secure information.
It relies on quantum key distribution (QKD), where encryption keys are transmitted via quantum particles.
Any attempt to eavesdrop alters the quantum state, revealing the intrusion immediately.
Unlike classical encryption, quantum cryptography is theoretically unbreakable.
Photons are commonly used to carry quantum keys across optical fibers or even via satellites.
Quantum cryptography ensures secure communication for governments, banks, and sensitive industries.
It exploits superposition and entanglement to guarantee data integrity and secrecy.
Researchers are developing global quantum networks for ultra-secure, long-distance communication.
Quantum cryptography could protect against future threats, including attacks from quantum computers.
By harnessing fundamental physics, quantum cryptography represents the ultimate frontier in secure communication.
