http://philsciarchive.pitt.edu/16203/
It is well known that there is a freedomofchoice loophole or superdeterminism loophole in Bell’s theorem. Since no experiment can completely rule out the possibility of superdeterminism, it seems that a local hidden variable theory consistent with relativity can never be excluded. In this paper, we…[Read more]

I still think the psychophysical connection is one of these problems. See my recent paper:

Dear Bob,
Thanks for your comments! I am sorry for not discussing your ideas in detail in my book. The reason is that I have not studied your CH solution very deeply, and I cannot give my own opinions on it. I will try to study your solution in the near future.
Best,
Shan

Quantum mechanics is an extremely successful physical theory due to its accurate empirical predictions. The core of the theory is the Schrodinger equation and the Born rule. The Schrodinger equation is linear and it governs the time evolution of the wave function assigned to a physical system. The Born rule says that the result of a measurement on…[Read more]


Shan Gao replied to the topic Does the psiepistemic view really solve the measurement problem? in the forum 2016 International Workshop on Quantum Observers 3 years, 8 months ago
Hi Jiri,
Thanks for your comments. I think you misunderstood the main idea of my paper. It does not aim to argue the impossibility of the psiepistemic view based on the KochenSpecker theorem. It only argues that the psiepistemic view does not provide a straightforward resolution or a dissolution of the measurement problem, as I clearly…[Read more]

Hi Ken,
Thanks again for your very detailed reply! I learned a lot about the retrocausal quantum models from them. I feel that such models seem more complex than Bohm’s theory. Maybe the reason is that there are no wave functions in them?
Best,
Shan

Hi Matt,
Thanks again for your further comments, most of which I agree. There is only one minor point I disagree. I still think the ontological models framework is more specific than Bell’s framework due to its second assumption. Even in the proof of the CHSH version of Bell’s theorem, although the ontic state λ is a random variable, it still…[Read more]

Hi Matt,
Thanks for your interesting comments, some of which I basically agree.
But I think you misunderstood my paper. The paper does not aim to show the (realist) psiepistemic view cannot solve the measurement problem. Rather, it only shows that the psiepistemic view does not provide a straightforward resolution or a dissolution of the…[Read more]

Thanks Arthur for your very detailed and helpful comments. I have learned much from these comments. I will improve my paper according to them. Best, Shan

Thanks Mark and Ken for your further comments. I have not thought too much on retrocausal models. I would like to know whether quantum randomness is also inherent in these models, and how these models account for the randomness of measurement results. Best, Shan

Shan Gao replied to the topic Does the psiepistemic view really solve the measurement problem? in the forum 2016 International Workshop on Quantum Observers 3 years, 9 months ago
Thanks Mark and Ken for your very helpful comments. I will need more time to think about them. For now I think Ken’s explanation seems to require the deny of the existence of free fill and essential randomness and have to resort to superdeterminism. Best, Shan

Shan Gao started the topic Does the psiepistemic view really solve the measurement problem? in the forum 2016 International Workshop on Quantum Observers 3 years, 9 months ago
It is widely thought that the psiepistemic view provides a straightforward resolution or even a dissolution of the measurement problem. In this paper we argue that this is not true. In order to explain the collapse of the wave function merely as a process of updating information about the underlying physical state, this view requires that all…[Read more]

Shan Gao replied to the topic How to solve the structured tails problem of dynamical collapse theories? in the forum 2016 International Workshop on Quantum Observers 3 years, 9 months ago
Thanks for your comments, Kelvin. It seems that you did not really understand my solution, which is different from the solution discussed in your paper. In my solution, there are no “zombie tails”. The observer being in the superposition has only one mind with the unique mental content. The key point is that according to my assumption about viv…[Read more]

Shan Gao replied to the topic Can Bohm's theory really solve the measurement problem? in the forum 2016 International Workshop on Quantum Observers 3 years, 9 months ago
Thanks for your further clarification, Peter. I still think that your assumption that the relative positions of the particles determine the measurement outcome requires a wholly new hiddenvariables theory which is different from Bohm’s theory.
Consider your example. If after being measured by the SternGerlach magnet, the two separated wave…[Read more]
