\(((5,6,2))\) qubit code[1]

Description

Six-qubit cyclic CWS code detecting a single-qubit error. This code has a logical subspace whose dimension is larger than that of the \([[5,2,2]]\) code, the best five-qubit stabilizer code with the same distance [2].

Its codeword stabilizer consists of all cyclic shifts of \(ZXZII\). It's automorphism group is of size 3840 and given in Ref. [1] (see also [3; Corr. 18]).
