1. A method to build a lookup decoder for mapping error syndromes based on quantum-stabilizer code to corresponding error corrections, the quantum-stabilizer code executing on a quantum computer, the method comprising:
enumerating a subset of error syndromes up to a maximum error weight based on the quantum-stabilizer code;
iterating through the subset of error syndromes to compute an error state of highest probability for each error syndrome of the subset, the error state defining error in a qubit register of the quantum computer; and
for each error syndrome of the subset of error syndromes, storing in classical computer memory an error correction based on the error state of highest probability and mapped to that error syndrome.
