Everything you said is right, except the part about quantum networks needing to do physical circuit switching. For example, consider a series of quantum routers. Each just continuously builds entanglement with its neighbors. When you want to send a qubit to a destination, a path is calculated and routers along the path perform entanglement swapping until you and the receiver share an EPR pair. Then you use that EPR pair to teleport the qubit to the receiver. No cables get moved; it's just changing which qubit pairs are measured in the Bell basis. ...Admittedly this is way beyond current capabilities. It basically requires the routers to be error corrected quantum computers (you need to do entanglement distillation to pump noise out of the system).
