I should have mentioned the previous work by Hennrich et al. you linked. As for Many Worlds, I only mentioned it since the review I read indicated that this experiment disproved it. In fact I just finished reading the book Something Deeply Hidden by Sean Carroll. in which he spent a lot of time writing about the Many World hypothesis. In any case I still do not see what being able to follow that the quantum jump from the ground state to an excited state occurs continuous, coherent and deterministic, means in relation to the “Collapse of the wave” hypothesis.

I am a retired Prof in Molecular Biology but I have a long standing interest as an outsider in Physics and Astronomy. I read recently about Quantum Trajectory Theory and a new experimental result in that field by Markus Hennrich and Adan Cabello , which I don't really understand. They measured electrically trapped strontium ions in superposition. They saw a smooth, gradual change in state rather than the abrupt snap of the predicted collapsing wave function. The review I read said that this went against the "many world" hypothesis. Could someone explain this to me? Thanks. Larry
