Preparation of photonic Fock state using bichromatic adiabatic passage under dissipative environment

Abstract

We propose a potentially practical scheme for generating the controllable photonic Fock state in a cavity by using the bichromatic adiabatic passage technique in the atom-cavity-laser system under dissipative environment. By numerically simulating the quantum dynamics of the whole system, we demonstrate quantitatively that the maximal probabilities of the Fock state can be achieved by elaborately adjusting the peak amplitudes of the laser's Rabi frequency and the detuning between the laser frequency and the atomic transition frequency. In addition, we have also shown that the atomic and cavity dissipations play different roles in the preparation of the Fock state inside the cavity. The experimental feasibility and challenge are justified using currently available technology. (C) 2014 Optical Society of America
