Dense Coding with Nonmaximally Entangled Cluster State via Local Measurement

We present two schemes for dense coding with nonmaximally entangled cluster state via local measurement. The average amounts of information are unique from the different two schemes. The average amount of information transmitted from Alice to Bob depends not only on the measurement angle θ, but also on the superposition coefficients of the state. For a given nonmaximally entangled cluster state, the supervisor can control the average amount of information transmitted from the sender to the receiver by adjusting the measurement angle.
