Gnu code
text:
In quantum information, the gnu code refers to a particular family of quantum error correcting codes, with the special property of being invariant under permutations of the qubits. Given integers g, n, and m, the two codewords are where | D k m ⟩ are the Dicke states consisting of a uniform superposition of all weight-k words on m qubits, e.g. The real parameter u = m g n scales the density of the code. The length m = g n u , hence the name of the code. For odd g = n and u ≥ 1 , the gnu code is
