Right now the Quantum Error Correction Kata is limited to Bit Flip Code. However there exists codes which correct for Sign Flip and also Shor's 9 qubit code which corrects for an arbitrary single qubit error (plus other further developments on this). I was thinking of extending the QEC_BitFlip Kata into a general QuantumErrorCorrection Kata which includes other error correcting codes besides Bit Flip. Please let me know if you might be interested in that?

We could have Part 2: On the Sign Flip Code and Part 3: on Shor's 9 qubit error correcting code and further developments on that.
