Abstract
A system with methods to be integrated as a quantum-communication firewall solution. The system is implemented with technology in combination of background-noise analysis, phase-shifting operation, phase-combination operations, and a proprietary data-synchronization mechanism. Thereby, through an optical communication channel with such a quantum-communication firewall solution, a conventional quantum communication system is not only capable of resisting specific spectrum attacks within a quantum communication channel, but also capable of countering a malicious optical source.
