    Undergrad Help me understand indeterminism in standard quantum mechanics

    Some in the quantum reconstruction program have aligned themselves with QBism as explained in these two papers: Berghofer, P.: Defending the quantum reconstruction program. European Journal for Philosophy of Science 14, 47 (2024). https://link.springer.com/article/10.1007/s13194-024-00608-2...

    Undergrad Help me understand indeterminism in standard quantum mechanics

    Here is a nice explanation of the PBR theorem by Maudlin: He only acknowledges the assumption of statistical independence, so you need to read the PF threads in post #14 above.

    So, you need this assumption in addition to the more fundamental assumption that we're looking for a probability theory to start with, which is (as shown by the QRP) the real mystery. His ISP must replace Darrigol's correspondence requirement, which is intuitive per the QRP (see Darrigol's...

    dBB has the pilot wave for superluminal influence in accord with the predictions of QM. I have not seen Barandes propose any corresponding mechanism. And he replaces causality with ... ? I was just repeating what Jacob said in the video. The mystery of the Bell-inequality-violating...

    Graduate Understanding Barandes' microscopic theory of causality

    The (current) quantum reconstruction program (QRP) began with Hardy's reconstruction of QM "From Five Reasonable Axioms" (https://arxiv.org/abs/quant-ph/0101012) in 2001. For a history of such attempts see: "Information and the Reconstruction of Quantum Physics," G. Jaeger, Annalen der Physik...

    Undergrad Help me understand indeterminism in standard quantum mechanics

    Turns out the probabilistic (indeterministic) nature of quantum mechanics (QM) follows from the discrete outcomes. I can't explain all the details in a short post here, but you can see more starting at about the 6-min mark in my video: Just ignore the context. I'm going to refer to work by...

    Here is a Short called Entanglement: The Indivisible Stochastic Approach: I don't see that Jacob provides any mechanism explaining the spacelike, Bell-inequality-violating correlations of his two entangled qubits. And when he says there is a common cause for the entanglement, so what? We...

    Insights Quantum Entanglement is a Kinematic Fact, not a Dynamical Effect

    Thnx for your comment, DaTario! The "kinematics" of QM per quantum information theory is its Hilbert space structure. For example, the qubit can be used to represent 'average-only' distribution of momentum along the detector of the double-slit experiment, 'average-only' transmission of energy...

    Granting ontological status to the wave function is an example.

    "Hidden variable" accounts are one type of constructive explanation.

    Graduate Understanding Barandes' microscopic theory of causality

    Here are two serious shortcomings that Albert points out: I've been researching quantum foundations since 1994 and I've seen my colleagues propose many such hypothetical ways to "fix quantum mechanics." I have yet to see any such ideas completed as promised. I doubt Jacob's idea will do any...

    Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality

    You are correct, there is a counterintuitive consequence of the observer-independence of h corresponding to the relativity of simultaneity, i.e., the counterintuitive consequence of the observer-independence of c. The relativity of simultaneity represents a change in our view of Newtonian space...
