    "abstract": "Every measurement leaves the object in a family of states indexed by the\npossible outcomes. This family, called the posterior states, is usually a\nfamily of the eigenstates of the measured observable, but it can be an\narbitrary family of states by controlling the object-apparatus interaction. A\npotentially realizable object-apparatus interaction measures position in such a\nway that the posterior states are the translations of an arbitrary wave\nfunction. In particular, position can be measured without perturbing the object\nin a momentum eigenstate.",
