Quantum Mechanics as Quantum Information

  1. Apr 25, 2014 #1
    Is there a thread on this forum that discusses this paper?
    It would suggest that the quantum wavefunction is a representation of our state of knowledge of a system. Is this an accepted view?

    There are various proposals in this spirit.

    One defintion of an epistemic view is given by http://arxiv.org/abs/0706.2661 (Found. Phys. 40, 125 (2010)).

    Explicit constructions of epistemic interpretations are given by
    http://arxiv.org/abs/1201.6554 (Phys. Rev. Lett. 109, 150404)
    http://arxiv.org/abs/1303.2834 (Phys. Rev. A 88, 032111 )

    Limitations on epistemic interpretations are found in
    http://arxiv.org/abs/1111.3328 (Nature Physics 8, 475–478 (2012))
    http://arxiv.org/abs/1208.5132 (Phys. Rev. Lett. 110, 120401)

    Regardless of interpretation issues, one version of the epistemic view led to a very nice way to prove the quantum de Finetti representation theorem.

    There are several definition of "epistemic". In addition to Harrigan and Spekkens definition referred to above, other proposals are:
    http://arxiv.org/abs/1301.3274 (Rev. Mod. Phys. 85, 1693) - this is closest to the paper in the OP
    http://arxiv.org/abs/1107.5849 (Phys. Rev. A 88, 052130)

    It is also interesting to see an "epistemic" argument applied to Bohmian mechanics

    Wow! That's going to keep me busy all weekend! Thanks.
