Quantum cryptography enhances security through the principles of quantum mechanics, enabling secure communication channels resistant to eavesdropping. By utilizing quantum key distribution (QKD), parties can generate encryption keys that are theoretically immune to interception. If an attempt to measure the quantum state occurs, it disrupts the transmission, thereby alerting users to potential security threats. This state-of-the-art technology bolsters the confidentiality and integrity of sensitive information, signaling a significant advancement in secure communications.
