Digital System Design for Quantum Error Correction Codes

Table 2

List of syndromes, error detected, and action to correct the error.

Syndrome	Error	Action
00	No error	No action
01	3^rd qubit flipped	Apply σx to the 3^rd qubit
10	2^nd qubit flipped	Apply σx to the 2^nd qubit
11	1^st qubit flipped	Apply σx to the 1^st qubit
