Maximal Entanglement and Teleportation using an Arthurs-Kelly type Interaction for Qubits
arXiv:1612.03405 · doi:10.1140/epjd/e2018-90420-4
Abstract
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.
