摘要：

The transmission rate of classical information sent through the thermalizing quantum channel is considered. The entanglement-assisted capacity, the Holevo capacity and the capacity of the quantum dense coding are analytically obtained and their properties are investigated. It is found that due to the unlimited use of quantum entanglement, the entanglement-assisted capacity becomes much greater than any other capacities when the channel noise is very large and the signal power is very weak.
