- This article in ars technica is about this paper, in which a quantum interference experiment is performed that, in the most straightforward interpretation, involves superpositions of states where "event A preceded event B" and "event B preceded event A". This is in the same mind-zapping vein as quantum eraser experiments. I haven't read this in detail, but my typical takeaway from these things is two-fold: (1) the math of the usual quantum mechanics formalism is in excellent agreement with...
