Local Hidden Variable Theories Agree With Quantum Mechanics After All…

ABSTRACT
In this talk, I prove that local hidden variable theories actually agree with quantum mechanics by giving explicit proofs and numerical demonstrations based on my paper "Local Hidden-Variable Models That Agree with Quantum Mechanics for All Systems." This paper disproves J.S. Bell's 1964 attempt to prove that local hidden variables are not compatible with quantum mechanics via his Bell inequality violations, and shows that all the experimental data that seemingly supports his results actually supports these new results instead. Specifically, I show that mean values of products of local deterministic measurement functions can always be found to agree with the expectation values predicted by quantum mechanics. This is true whether the state is entangled or not, in any multipartite system, whether mixed or pure. I give explicit constructions for this in all multipartite systems, thus disproving Bell by example in all cases, and disproving all related results such as the famous CHSH inequalities. Thus EPR (Einstein, Podolsky, and Rosen) were correct at least in principle, and whether or not our universe actually “runs on” local hidden variables, this discovery opens the door to new technologies even as it formally disproves all quantum advantage in quantum computers. Skeptical? Come and see for yourself!
BIOGRAPHY
Dr. Hedemann is an inventor and researcher in quantum information and quantum computation, currently teaching as a Lecturer of Physics at Stevens Institute of Technology, before which he was a Visiting Assistant Professor of Physics at the New York Institute of Technology (NYIT). Prior to that, he completed the Postdoctoral Fellowship in Quantum Information Science at The Johns Hopkins University Applied Physics Laboratory (JHUAPL), and before that he taught as an Adjunct Professor of Physics at Hunter College (CUNY). He received his Ph.D. in Physics from Stevens Institute of Technology in 2014 as an Innovation and Entrepreneurship Doctoral Fellow, and was part of the Quantum Information and Quantum Optics group headed by Dr. Ting Yu. Before that, he earned his Bachelor of Science in Physics from University of Maryland Baltimore County (UMBC) in 2008.
