    "abstract": "System of 1/2 spin particles is observed repeatedly using Stern-Gerlach\napparatuses with rotated orientations. Synthesis of such non-commuting\nobservables is analyzed using maximum likelihood estimation as an example of\nquantum state reconstruction. Repeated incompatible observations represent a\nnew generalized measurement. This idealized scheme will serve for analysis of\nfuture experiments in neutron and quantum optics.",
