Abstract
Two schemes for controlled dense coding with a generalized GHZ-type 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. The results for the average amounts of information are unique from the different two schemes.
