Why the Quantum

6/29/2018

3 Comments

 
To answer Wheeler's question "Why the quantum?" via quantum information theory according to Bub, one must explain both why the world is quantum rather than classical and why the world is quantum rather than superquantum, i.e., "Why the Tsirelson bound?" We show that the quantum correlations and quantum states corresponding to the Bell basis states, which uniquely produce the Tsirelson bound for the Clauser-Horne-Shimony-Holt quantity, can be derived from conservation per no preferred reference frame (NPRF). A reference frame in this context is defined by a measurement configuration, just as with the light postulate of special relativity. We therefore argue that the Tsirelson bound is ultimately based on NPRF just as the postulates of special relativity. This constraint-based/principle answer to Bub's question addresses Fuchs' desideratum that we "take the structure of quantum theory and change it from this very overt mathematical speak ... into something like [special relativity]." Thus, the answer to Bub's question per Fuchs' desideratum is, "the Tsirelson bound obtains due to conservation per NPRF."

Thanks for writing a book about the block universe! It has been very difficult to find expositions of general relativity that use this approach.

I specifically commented on this blog post because I think Dirac's 1931 unrecognized achievement of Wheeler's goal of deriving the quantum would interest you. It is described in my post at http://www.physicsspot.com/2018/01/30/deducing-the-quantum/

If you would like to deepen our discussion about physical reality, please contact me. I am writing a book that pulls the various domains of physics into a three-level unified view.

Thnx for sending the link. I read the post and do not see its relevance to block universe. What am I missing?
