The purpose of this paper is to describe what Reverse Logistics is, what is it benefits, the status quo of Reverse Logistics in china and its difficulties, and give some suggestions and countermeasures on how to manage Reverse Logistics successfully under China's current situation.展开更多

The capacity of a classical channel is essentially characterized by maximum transmission rate of classical information. However, in quantum information theory, several capacities can be defined for a quantum channel based on the type of information being sent.展开更多
