Abstract

Two-mode Schrödinger cats consisting of two and four coherent-state terms are considered. It is shown that they are closely related to the quadrature entangled EPR pair. The properties of their wave functions are investigated from their aspects of entanglement. It is shown that at certain parameters the entangled properties of the two-mode Schrödinger cats allow for good teleportation fidelity. A theoretical generalization to the teleportation of two qubits is also discussed.
