Classification: CPC G  H | IPC G  H

Claim 4:
5. The method of claim 4, the correction operator Ω is obtained by a method, including:
transforming each correctable error Eτ of a correctable error set ε by the encoding Qen to a coset of error of each correctable error Eτ in the second stabilizer Ĉ in the intrinsic coordinate, wherein the coset of error is a k-qubit spinor τ;
building a first complete set Pin in the second stabilizer Ĉ in the intrinsic coordinate, wherein the first complete set Pin is consisting of a unique input coset β solely chosen from every block Γα, and the first complete set Pin contains all the spinors τ;
building a second complete set Pout in the second stabilizer Ĉ in the intrinsic coordinate, wherein the second complete set Pout is consisting of a unique output coset α solely chosen from every block Γα;
formulating a transfer amplitude T; and
wherein each of the submatrices Mαβ of the encoding Qen represents as a sequential product by entries of the submatrices Mαβ (xαβ), the output coset α, the K-qubit quantum gate M and the input coset β.
