Thanks for the article. I am aware of this work. It is an interesting idea and proposal. Experiments in the last 40+ years have repeatedly shown that Quantum Theory’s experimental predictions are correct, and Local Hidden Variable Theories’ experimental predictions are wrong. However, as my article also pointed out “physicists are still not completely satisfied with QT, especially in its explanation of what is happening in nature, and not just on whether it can predict accurately the results of measurements.”
For example, some people have speculated that we need to take consciousness into account in order to understand what is happening in nature. As mentioned in your referenced article, the first person to suggest that was Eugene Wigner, the 1993 Nobel Physics Laureate, based on some earlier idea by John von Neumann. One of the subsequent main advocates is Henry Stapp, another physicist from UC Berkeley (see, e.g., https://en.wikipedia.org/wiki/Henry_Stapp), who also made the comment that Bell’s Theorem is “the most profound discovery of science.”
The recent work from the Center for Quantum Dynamics at Griffith University in Australia mentioned in your referenced article is a more detailed proposal along this line using quantum computers as part of an experiment. It is an interesting proposal and depending on the outcomes of future experiments similar to this, it could shed important information on what is happening in nature and how we explain what is happening in nature, besides predicting accurately the results of experiments.
So my understand will be different from the 2020 June letter by my good friend. How Trump handle HK crisis will have heavy weight of my Nov vote.
