摘　　要：We present a new method called the permutation matrix method to perform dense coding using Greenbezger-Horne-Zeilinger （GHZ） states. We show that this method makes the study of dense coding systematically and regularly. It also has high potential to be realized physically.We present a new method called the permutation matrix method to perform dense coding using Greenbezger-Horne-Zeilinger （GHZ） states.
