Claim 8:
9. The method for resisting quantum perturbation threats to quantum communication devices according to claim 6, wherein the mechanism of bias correction on the quantum computing device comprises:
a) setting up a parameter space based on a found exception point in a non-Hermitian system;
b) simulating to introduce complete corresponding parameters of the parameter space clockwise so as to derive a quantum state;
c) simulating to introduce complete corresponding parameters of the parameter space counterclockwise so as to derive another quantum state;
d) confirming the above two derived quantum states satisfy parity-time symmetry;
e) deriving an expected direction where a perturbation shall come according to the corresponding non-orthogonal bases from the derived quantum states satisfying parity-time symmetry, and determining whether the observed direction where a perturbation comes fits the expected direction via making use of a PT-symmetry quantum sensor;
f) once the operation d) confirmed that the above two derived quantum states satisfy parity-time symmetry and the operation e) also determined that the observed direction where a perturbation came was not in expectation, the states derived from the parameter space will be treated as corrected quantum states in a local system, otherwise the system will stop the current quantum communication; and
g) making use of the corrected states to derive a corresponding system wave function via Schrödinger equation, and then performing First order corrections of time-independent perturbation theory based on the derived system wave function.
