Abstract
The simplest non-dissipative 2-level atom system, a qubit, excited by a train of resonant n-Gaussian laser pulses is investigated. This concerns examination of the averaged atomic variables, the intensity-intensity correlation function, and the transient fluorescent radiation. Analytical formulas for the above expressions are obtained. Computational results show that the transient spectra with the initial ground and coherent atomic states exhibit asymmetric Mollow structure with dip structure, dense oscillation, and narrowing, and depends on the pulse number (n), the repetition time (τR), and the observed time.

The purpose of the present paper was to investigate both the transient fluorescent spectrum and the photon anti-bunching effect for a non-dissipative qubit driven by a train of resonant Gaussian laser pulses
For a single 2-level atom of excited and ground states, |ei and | gi, respectively, and of transition frequency ωo interacting with a resonant laser pulse of circular frequency ωo and of arbitrary shape f (t), the total Hamiltonian operator has the form
Summary
Controlling the state dynamics of a 2-level atom (qubit) is achieved by investigating its interaction with short laser pulses; control its desired final state [1,2,3]. For non-dissipative pulsed-driven qubits, transient fluorescent spectrum have been investigated for various pulse shapes Investigation of pulsed-driven qubits are essential for topics, like quantum computation and quantum information sciences The purpose of the present paper was to investigate both the transient fluorescent spectrum and the photon anti-bunching effect for a non-dissipative qubit driven by a train of resonant Gaussian laser pulses.
