    "abstract": "We study a quantum state transfer between spins interacting with an arbitrary\nnetwork of spins coupled by uniform XX interactions. It is shown that in such a\nsystem under fairly general conditions, we can expect a nearly perfect transfer\nof states. Then we analyze a generalization of this model to the case of many\nnetwork users, where the sender can choose which party he wants to communicate\nwith by appropriately tuning his local magnetic field. We also remark that a\nsimilar idea can be used to create an entanglement between several spins\ncoupled to the network.",
