Based On Asymmetric Multi-body Entangled States Of Multi-and Control Of Quantum Dense Coding Scheme

We realize the multi-party quantum dense coding scheme and the controlled quantum dense coding scheme, in the case of non-symmetric Hilbert spaces of the senders and receiver's particles sharing the quantum channel. In the scheme between multi-sender and one-receiver, we show that the amount of classical information transmitted from multi-sender to the one-receiver is improved. By making use of the projective measurement, we realize the quantum dense coding scheme between one-sender and multi-receiver. In the controlled quantum dense coding scheme, we give a way of quantum controlling classical information amount in order to adjust the amount of classical information to float between the capacity of the particle's information and the capacity of quantum channel.
