| Abstract: | A class of the single-mode excited GHZ-type entangled coherent states (EGHZECSs) are presented. we exhibit the remarkable
properties of the single-mode EGHZECSs, depended on the excitation photon number, such as entanglement and nonlocality via
investigating their concurrence of entanglement and examining their violation of CHSH inequality. Finally, we propose how
to generate the EGHZECSs by using cavity QED and quantum measurement and by using BBO crystal and single-photon detection
technique, respectively. |
