We study the control of spontaneous emission in four-level atomic system driven by two fields. We show that with the variation of dynamical variable, namely, Rabi frequency, a wide variety of spectral behavior can be obtained, including extreme spectral narrowing. In our system, the spectrum of the spontaneous emission is independent of the phase associated with microwave field.

We present a scheme to implement a quantum [Formula: see text] gate for two-atom trapped in distant cavities connected via an optical fiber. In the whole process, the atomic system, the cavity modes and the fiber are not excited ensuring that the operation is insensitive to atomic spontaneous emission, cavity decay and the fiber loss. This scheme is significant for distributed and scalable quantum computation.
