Abstract
We propose a protocol to generate the cluster
states of four Λ-type three-level atoms trapped in distant
cavities by using interference of polarized photons. The protocol
use the effects of quantum statistics of indistinguishable photons
emitted by the atoms inside optical cavities. This makes the
protocol more realizable in experiments.
