I'd rather not. I do not know anything about non magical science.
Ghost are classified as magical beings. I mean there are technical classifications for a lot of magical creatures like centaurs, ghosts, werewolves, vampires.
Going back to the original question, I was told, rather snottily, that it was magic, and having pocked around, it does feel like magic. Now this quantum physics might move through space, time, create duplicate hotels, but would it really create Valentine's Day decorations and food? If it does, then it sounds like magic but with another name.
