This is such a beautiful theoretical idea (a type of "natural" error correction which protects the qubits without having to deal with the exorbitant overhead of error correcting codes). It is very disheartening and discouraging and just plain exhausting that there has been so much "data manipulation" in this subfield (see all the other retracted papers from the last 5 years mentioned in the article). I can only imagine how hard this must be on the junior scientists on the team who have been swept into it without much control.
