Minev's PhD thesis, "Catching and Reversing a Quantum Jump Mid-Flight" and the Nature article that summarized it (arXiv) showed that one could monitor the quantum state of transitions that occurred across a connection between two microwave cavities at low temperature. The descriptions I've seen so far have argued that it challenges the Copenhagen interpretation because it show that the transitions occur over finite time. That's been asked and answered (I never thought that was being claimed by anyone, but apparently I'm wrong. I was under the impression that the conjugate energy-time relationship and the Heisenberg Principle meant that the time for energy transitions needed to be non-zero.)
Contrariwise, I think the many-worlds interpretation is more directly challenged because it posits a split which gains independent existence.
So I suppose my questions are (1) whether people arguing about the fundamentals are paying attention to this set of experimental results and (2) if there were a forum where we might view those discussions? The one SE.physics discussion so far focused on potential challenges to the supposed instantaneous nature of transitions.
