The experimental setup, where these protocols could be implemented, is typical of microwave cavity quantum electrodynamics. Our proposal extends to cavity QED the technique of quantum reservoir engineering, origi- nally applied to trapped ions. It offers a convenient way of implementing quantum mechanical dynamics and state preparation. Besides constituting a robust procedure for generating nonclassical states of the electromagnetic field in cavities in a steady-state regime, it might be useful for quantum networking with continuous variables in the mi- crowave regime. by reconstructing the corresponding Wigner function, by suitably generalizing the schemes proposed in [50]. 11 Support by the European Commission (EMALI, MRTN-CT-2006-035369; SCALA, Contract No. 015714) Acknowledgments [1] D.
