What does this imply for https://scirate.com/arxiv/1608.00263? I'm guessing they still regard it as valid (it is ref [14]), but just too hard to implement for now.

James Wootton published A repetition code of 15 qubits
The repetition code is an important primitive for the techniques of quantum error correction. Here we implement repetition codes of at most $15$ qubits on the $16$ qubit \emphibmqx3 device. Each experiment is run for a single round of syndrome measurements, achieved using the standard quantum technique of using ancilla qubits and controlled operations. The size of the final syndrome is small enough to allow for lookup table decoding using experimentally obtained data. The results show strong evidence of error correction, and also give insight into the nature of noise in the device.

Seems so obvious now you say it! Well done for trying this out.

Do you know how the results compare to Wen style stabilizers, where both plaquette and vertex stabilizers alternate between two Paulis? I guess using Y and Z would be best for biased noise, given your results.
