What is Faithful Measurement?

  1. Jan 1, 2015 #1
    What is ''faithful measurement'' in Quantum Mechanics exactly. I have seen this expression in Kochen-Specker Theorem.

    To quote wiki (http://en.wikipedia.org/wiki/Kochen–Specker_theorem:
    In this case "subquantum element" is a supposed "hidden value".
    Since KS argues against hidden values and hidden values are not how most physicists interpret QM, it's probably not correct to say that "faithful measurement" is part of QM - only as part of the study of QM.

    thanks for your reply. but again I cannot understand the exact definition of faithful measurement :/

    It simply means that the measurement is the result of a specific (non-stochastic) function of some observable.
