Homework Help: Density matrix

  1. Oct 20, 2007 #1
    1. The problem statement, all variables and given/known data

    Suppose a source emits silver atoms, which are sent through
    three different types of Stern-Gerlach devices, each of them is either sorting
    the atoms along the x, y or z axis. If we preform a measurement along the
    z or y axis, the atoms are sorted in the ” + ” direction with probability 3/8,
    while if we sort along the x axis, the ” + ” direction occurs with probability

    Find the density operator of this source

    Can someone help me get started? How do I find out what the source is composed of?
