Query: Maximal Entanglement and Teleportation using an Arthurs-Kelly type
  Interaction for Qubits   We study entanglement generation between a system qubit and three apparatus
qubits using an exactly solvable 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 protocol to transfer the unknown state of
the system onto one of the apparatus qubits which can then be sent elsewhere
via a quantum channel. This protocol can be seen as an alternative
teleportation scheme.
