A semiclassical model is presented for characterizing the linear response of elementary quantum-optical systems involving cavities, optical fibers, and atoms. Formulating the transmission and reflection spectra using a scattering-wave (transfer-matrix) approach, the calculations become easily scalable. To demonstrate how useful this method is, we consider the example of a simple quantum network, i.e., two cavity-QED systems connected via an optical fiber. Differences between our quasiexact transfer-matrix approach and a single-mode, linearized quantum-optical model are demonstrated for parameters relevant to recent experiments with coupled nanofiber-cavity-QED systems.A semiclassical model is presented for characterizing the linear response of elementary quantum-optical systems involving cavities, optical fibers, and atoms.

Simple scheme for generating an n -qubit W state in cavity QED

Zhi Jiao Deng, Mang Feng, K. Gao

A simple scheme is proposed to generate an $n$ -qubit $W$ state in cavity QED. Conditioned on no photon leakage from the cavity, the $n$ -qubit $W$ state can be generated by resonant interaction between atoms and the cavity if the cavity is initially prepared in the single-photon state and all the atoms are in the ground states. We check the time evolution of the system involving decay, and show that, since the required interaction time is very short, with present cavity QED techniques, the success probability of our scheme is almost unity.A simple scheme is proposed to generate an $n$-qubit $W$ state in cavity QED.
