Permutation Matrix Method for Dense Coding Using GHZ States
Jin Rui-Bo, Libing Chen, Faqiang Wang, Zhi-Kun Su · Chinese Physics Letters · 2008
We present a new method called the permutation matrix method to perform dense coding using Greenberger–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.
