Intrinsic Efficiency

We present a scheme for teleporting a certain class of six-particle state via an eight-particle cluster state as quantum channel. In our scheme, the sender merely needs to perform an eight-particle von-Neumann projective measurement, and the receiver gives a corresponding general evolution to restore the original state. Our scheme is a deterministic scheme. Compared with other schemes proposed before, our scheme possesses higher intrinsic efficiency.

Trap System

We present an alternative scheme for generating the N-qubit cluster state in the ion trap system. This scheme is based on adiabatic passage and thus is insensitive to the small fluctuations of the system parameters. During the process of evolution, quantum information transfer occurs only between the ions, and the collective vibrational mode remains in the vacuum state without excitation. Thus, the scheme is robust against phonon decoherence.

Amount Of Information

Two schemes for controlled dense coding with a one-dimensional four-particle cluster state are investigated. In this protocol, the supervisor (Cliff) can control the channel and the average amount of information transmitted from the sender (Alice) to the receiver (Bob) by adjusting the local measurement angle θ. It is shown that the results for the average amounts of information are unique from the different two schemes.
