Abstract
We respond to the criticism of our paper ‘Generation of cluster-type entangled coherent states’. In the original paper, we remove the explicit time dependence from the interaction Hamiltonian by transforming to a rotating frame for the field operators, which is also done to quantum dots embedded in a microcavity (Djuric and Search 2007 Phys. Rev. B 75 155307). We thank Wei Haihong and Wang Faqiang for pointing out that cluster-type entangled coherent states (CTECS) cannot be obtained with the original time-dependent Hamiltonian under certain parameter condition λ ≪ |χ|. For the original field operators, we present a new method to generate CTECS in the same system.
