摘 要: | We investigate the dense coding in the case of non-symmetric Hilbert spaces of the sender and receiver‘s particles sharing the quantum maximally entangled state. The efficiency of gaining classical information is also considered.We conclude that when a more level particle is with the sender, she can obtain a non-symmetric quantum channel from a symmetric one by entanglement transfer. Thus the efficiency of information transmission is improved.
