A system and method for resisting quantum perturbation threats to quantum communication devices, especially to a quantum cyber security technology for sensing external perturbations to a quantum communication device and for performing perturbation-bias correction in a non-Hermitian system. Through observing and analyzing on a resonant model, such technology not only senses suspicious potential variation which may make potential energy related to a quantum computing device be changed, but also enhances to implement a correction policy coupling to an information-correction sub-system. Meanwhile it patterns the detected perturbation threats with relative permeability so as to provide early protection on a quantum communication device for resisting a risky perturbation threat.
