Abstract
A protocol is proposed for generating three-particle Knill-Laflamme-Milburn (KLM) states in a system composed of two frequency-tunable flux qubits and a coplanar waveguide resonator. With the help of the counter-rotating interaction, the protocol for generating three-particle KLM states can be realized. The numerical results reveal that the protocol is robust against the effects induced by decoherence and frequency-tuning operations. It is hope that the protocol provides an alternative method to generate entangled states.
