There’s nothing that distinguishes two particles that share a quantum state. You can’t say it’s the same particle and you can’t say it’s not.

They just can't be part of the same quantum system when they do so, for definitions of "quantum system" that some people made up at one point and are (apparently) free to redefine at will. This is "teleportation" in the same sense that Chinese skateboards with electric motors and debatably-safe lithium batteries duct-taped to them are "hoverboards."
