John Cramer has been pointing this out for years (since the 1980s I think): "The Transactional Interpretation of Quantum Mechanics and Quantum Nonlocality" https://arxiv.org/abs/1503.00039 Also, Bell's inequality shows the state vector is nonlocal, and and that implies causality violation in relativity. Third, quantum information theory has retrocausality in the form of negative entropy: "Negative entropy in quantum information theory" https://arxiv.org/abs/quant-ph/9610005 Too many things pointing in the same direction. This is the right way to look at it.

Without reading the paper or watching the video. > 1) What does it mean that entangled particles are supercorrelated? How can S(A|B) = 2 or -1? The density matrix does not have the same properties of a joint probability distribution, so quantum entropy doesn't really have the same properties of classical entropy. [1] > 2) The formula for Von Neumann entropy is S = -Tr(p log(p)), where p is the density matrix. How do you take a log of a matrix? The log of a matrix is defined as the inverse of the matrix exponential. The matrix exponential can be defined as the usual power series, only using…
