Observation is a stimulus that reaches objects which possess consciousness. To unravel the mystery we have to treat consciousness as a physical object. It isn't known what it is at all. We know neither what it is built of nor what its existence depends on, but assuming that it's something real will help us with our considerations. If a particular object is being observed, some information reaches consciousness. Then consciousness sends a feedback which moves with infinite speed. That information is e.g. some molecule. That molecule is in charge of quantum convolution.
