Quantum teleportation of arbitrary two-qubit state via entangled cavity fields

• We propose a scheme for teleportation of arbitrary two-qubit state.
• The entangled cavity fields are used as quantum entangled channel.
• The scheme is deterministic and direct without the help of the other atoms.

We propose a new protocol for quantum teleportation of an arbitrary two qubit state via continuous variables entangling channel. In our scheme two pairs of entangled light fields are employed. An outstanding characteristic of this scheme is that arbitrary state of two atoms is transmitted deterministically and directly to another pair of atoms without the help of the other atoms.
