摘要

Quantum cryptography provides unparalleled security in data transmission by exploiting the fundamental principles of quantum mechanics. However, real-world implementations remain vulnerable to eavesdropping attacks, including side-channel exploits and quantum state interception techniques. In this study, we propose a hybrid approach combining resonance-based electromagnetic shielding and phase-modulated photon encryption to enhance quantum communication security. Our research demonstrates that introducing adaptive interference fields prevents external interception while maintaining signal integrity. Additionally, embedding phase-modulated quantum states ensures that unauthorized parties cannot reconstruct encrypted transmissions without complete knowledge of the modulation parameters. Experimental simulations validate the effectiveness of these mechanisms, with security improvements exceeding conventional quantum key distribution protocols.
