    "abstract": "This paper presents a method for enumerating all encoding operators in the\nClifford group for a given stabilizer. Furthermore, we classify encoding\noperators into the equivalence classes such that EDPs (Entanglement\nDistillation Protocol) constructed from encoding operators in the same\nequivalence class have the same performance. By this classification, for a\ngiven parameter, the number of candidates for good EDPs is significantly\nreduced. As a result, we find the best EDP among EDPs constructed from [[4,2]]\nstabilizer codes. This EDP has a better performance than previously known EDPs\nover wide range of fidelity.",
