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.

Comment on ‘Generation of cluster-type entangled coherent states’

Haihong Wei, Faqiang Wang

We rectify some errors in the scheme of generating cluster-type entangled coherent states (CTECS) proposed by Tang (2009 J. Phys. B: At. Mol. Opt. Phys. 42 085502) in this comment. Furthermore, we find that no system can successfully generate CTECS by Tang's method.
