Study of controlled dense coding with some discrete tripartite and quadripartite states
Abstract
The paper presents the detailed study of controlled dense coding scheme for different types of and particle states. It consists of GHZ state, GHZ type states, Maximal Slice state, Four particle GHZ state and W class of states. It is shown that GHZ-type states can be used for controlled dense coding in a probabilistic sense. We have shown relations among parameter of GHZ type state, concurrence of the shared bipartite state by two parties with respect to GHZ type and Charlie's measurement angle . We have seen that tripartite W state and quadripartite W state cannot be used in controlled dense coding whereas states can be used probabilistically. Finally, we have investigated controlled dense coding scheme for tripartite qutrit states.
