Claim 0:
1. A system for resisting quantum perturbation threats to quantum communication devices, the system comprising: at least one processing unit, at least one memory coupled to the at least one processing unit, and
a) a first sub-system, for sensing a frequency spectrum related to wireless or optical communication to determine whether there is a quantum symmetry attribute broken in a local system, the first sub-system including:
1) an optical-resonant cavity module for deriving a harmonic oscillator to be simulated in an optical-resonant cavity based on a combination of phases observed from the sensed frequency spectrum;
2) a wave-function derivation module for deriving simulated wave functions according to the derived harmonic oscillator;
3) an exception-point derivation module for deriving possible exception points of a non-Hermitian system according to the derived simulated wave functions; and
4) a spectral analysis module for performing spectral analysis to discard the exception point which is occurred with zero-point energy;

b) a second sub-system, coupled to the first sub-system, for detecting tiny variation of gravity and slow-light phenomenon in a local environment when the first sub-system determines that there is a broken quantum symmetry attribute; and
c) a third sub-system, coupled to the second sub-system, for detecting an abnormal reduction of multiscale entropy in a non-Hermitian local system during a specific period when the second sub-system determines that there is tiny variation of gravity and slow-light phenomenon in the local environment;, wherein the system determines that there should be a quantum perturbation threat to the quantum communication device when all of the first sub-system, the second sub-system, and the third sub-system report abnormal events; and then the system performs a mechanism of bias correction on the quantum communication device so as to resist impacts of the quantum perturbation threat.
