    "abstract": "The retrodiction of spin measurements along a set of different axes is\nrevisited in detail. The problem is presented in two different pictures, a\ngeometric and a general algebraic one. Explicit measurement operators that\nallow the retrodiction are given for the case of three and four axes. For the\nVaidman-Aharanov-Albert case of three orthogonal axes the quantum network is\nconstructed for two different initial Bell states.",
