We put forward a fast scheme for one-step generation of maximally entangled Greenberger–Horne–Zeilinger (GHZ) states by superconducting quantum interference devices (SQUIDs) in cavity via Raman interaction. The scheme only requires a quantized cavity field and classical microwave pulses. One of the key advantages of our Raman-interaction scheme is that an improvement of overcoming decoherence for the preparation of the desired GHZ states can be achieved.

We investigate the entanglement of a degenerate Raman process involving two degenerate Rydberg energy levels of an atom interacting with a single-mode cavity field. We use the concurrence as an entanglement measure and show that long living entanglement can be obtained for certain choices of the system parameters.
