Quantum Cryptography
Quantum cryptography uses the principles of quantum mechanics to secure data transmission. It allows two parties to share a secret key, ensuring that any eavesdropping can be detected due to the unique nature of quantum states. When information is encoded in quantum bits (qubits), measuring these states alters them, revealing the presence of an intruder. This process enhances security beyond traditional methods, as the laws of quantum physics ensure that only the intended recipients can access the information without it being compromised. It represents a revolutionary advance in secure communication.

Quantum cryptography is a secure communication method that uses principles of quantum mechanics to protect information. It enables two parties to share encryption keys with the assurance that any eavesdropping will be detected. This is achieved through the behavior of quantum particles, which can exist in multiple states simultaneously. If someone tries to intercept the key, the quantum state changes, alerting the communicating parties. Unlike traditional encryption, which relies on complex algorithms and computational power, quantum cryptography leverages the laws of physics to ensure security fundamentally, making it potentially unbreakable.
