    "abstract": "We investigate the dense coding in the case of non-symmetric Hilbert spaces\nof the sender and receiver\u0027s particles sharing the quantum maximally entangled\nstate. The efficiency of classical information gain is also considered. We\nconclude that when a more level particle is with the sender, she can get a\nnon-symmetric quantum channel from a symmetric one by entanglement transfer.\nThus the efficiency of information transmission is improved.",
