We study entanglement generation between a system qubit and three apparatus qubits using an exactly soluble Arthurs-Kelly type model. We demonstrate the possibility of generating an EPR-like maximally entangled system-apparatus state, in which the second qubit of the usual EPR state is replaced by a three qubit state. We design a very simple teleportation protocol to transfer the unknown state of the system onto one of the apparatus qubits which can then be teleported via a quantum channel.
