Controlled Dense Coding with Six-particle Nonmaximal Graph State



Two schemes, with Von Neumann measurement and generalized measurement, for controlled dense coding are investigated by using a six-particle nonmaximal graph state. The results for the average amounts of information are unique from the different two schemes. The supervisor may control the average amount of information transmitted from the sender to the receiver by adjusting the local measurement angle.
