Abstract
In this Letter, we propose a scheme to generate atomic cluster states in optical cavity QED. In the scheme, the atomic spontaneous emission
is suppressed, and the fidelity is not affected by the imperfection of detection efficiency. We further research the successful probability and the
fidelity via numerical simulation by considering the influence of the possible noise.
