Generation of cluster-type entangled coherent states

We propose a method of generating cluster-type entangled coherent states (CTECS) using several single-mode cavities and an electron trapped in a moving quantum dot, assisted with a sequence of π/2 pulses on the electron. After the realization of simple electronic measurement, a series of CTECS representing nonlocal electromagnetic fields of cavities have been generated. Furthermore, we investigate the nonlocal properties of the generated CTECS based on the GHZ–Mermin argument.
