Construction

Construction of a [[27,20,3]] quantum code:
[1]:  [[40, 33, 3]] Quantum code over GF(2^2)
     Construction from a stored generator matrix
[2]:  [[27, 20, 3]] Quantum code over GF(2^2)
     Shortening of [1] at { 5, 7, 8, 9, 15, 19, 20, 21, 22, 33, 34, 36, 37 }

    stabilizer matrix:
