It is often assumed that the ancilla qubits required for encoding a qubit inquantum error correction (QEC) have to be in pure states, $|00...0>$ forexample. In this letter, we seek an encoding scheme, in which the ancillae maybe in a uniformly mixed state. We demonstrate our scheme experimentally bymaking use of a three-qubit NMR quantum computer. Moreover, the encoded statehas an interesting nature in terms of Quantum Discord, or purely quantumcorrelations between the data-qubit and ancillae.
