Free Will Theorem question
The Kochen-Specker Theorem says, if I understand it correctly, that the results of spin measurements cannot be predetermined independent of measurement. They get to this conclusion by describing 33 ...

Are all instances of quantum non-locality problem artifacts of the use of classical concepts in quantum physics?
Consider experiments involving entangled spins, say two-spin 1/2 particles in the singlet state:
$$\left|\psi\right> =\frac{1}{\sqrt{2}}\left[\left|\uparrow\downarrow\right> - \left|\downarrow\...

How to imagine wavefunction branching?
This is a question particularly geared toward the Many Worlds interpretation, but I think it could be translated to other approaches as well.
I am not sure I understand exactly what sort of events ...

Are there known paradoxes regarding a detector that was, before use, entangled with a particle it detects?
Is it possible to design a system where a detector is entangled with the particle state it detects (before it is detected), and to create a paradox from this?
Upon observance of a state by the ...

Why would the classical (local) correlation in Bell's experiment rule out the cosine of the angle?
This question expands on a specific detail of this previous question:
Why would classical correlation in Bell's experiment be a linear function of angle?
I would have commented on/answered that ...

Scan Quantum mechanics: Status of current research
I recently stumbled on a new interpretation of Quantum mechanics, called Scan Quantum Mechanics, given by Beatriz Gato-Rivera. She suggests a quantity called quantum inertia, which divides the ...

Justification for "which path" inference in Hardy's paradox?
I'm going over Hardy's paradox again recently and whenever I try to think about it I always get confused with the classical part of the analysis. Just as a brief summary, the setup of the paradox is ...

Why is the wavefunction not a hidden variable?
Consider the following standard case of an entanglement experiment:
We prepared two electrons A and B with states
$$\lvert A\rangle=a_1\lvert \uparrow\rangle+a_2\lvert \downarrow\rangle$$
$$\lvert B\...
