Can a quantum particle be at two locations? Better to say: A particle may not have a location at all. But when it does, it has only one (at least in this universe).pic.twitter.com/GEznxt3rNN

Heavy technicality. I'm not sure if I agree. It seems like we use the word "particle" for two different, yet related, concepts. A wave packet is usually considered to represent a "particle". And the other meaning is a point-like object, which doesn't strictly exist by the way.
that's what I'm saying.. point like object means an object with definite position, which can exist if it's in a position eigenstate, but in general a free "particle" is going to be a wave packet

So a packet becomes a particle only when it's bounded in some potential (of similarly bounded packets(...))?
