Table 2.
List of syndromes, error detected, and action to correct the error.
| Syndrome | Error | Action |
|---|---|---|
| 00 | No error | No action |
| 01 | 3rd qubit flipped | Apply σx to the 3rd qubit |
| 10 | 2nd qubit flipped | Apply σx to the 2nd qubit |
| 11 | 1st qubit flipped | Apply σx to the 1st qubit |
