\(((9,12,3))\) qubit code[1]
Description
Nine-qubit cyclic CWS code correcting a single-qubit error. This code has a logical subspace whose dimension is larger than that of the \([[9,3,3]]\) code, the best nine-qubit stabilizer code with the same distance [2].
Its codeword stabilizer consists of all cyclic shifts of \(ZXZIIIIII\).
The \(((9,12,3))\) qubit code can be combined to from an infinite family of distance-three qubit codes whose logical dimension is \(50\%\) larger than that of the optimal stabilizer code [3].
Decoding
Fault-tolerant scheme that converts the required POVM into 10 binary measurements whose redundancy is guaranteed by a classical code [4].
