Introduction to Quantum Error Correction and Fault Tolerance
... protect a qubit against single-qubit errors. If we assume that our codes are non-degenerate, then it is easy to obtain a lower bound of the number of qubits required for a code by counting the number of orthogonal 2D subspaces which are required. To correct for I (no error), and Xn, Yn and Zn on eac ...

Spacelike separation of each local measurement from both the distant setting choice and the distant measurement closes the locality loophole. In ...
