We propose a scheme of increasing quantum correlations for the cavity quantumelectrodynamics system consisting of two noninteracting two-level atoms eachlocally interacting with its own quantized field mode by bang-bang pulses. Weinvestigate the influence of the bang-bang pulses on the dynamics of quantumdiscord, entanglement, quantum mutual information and classical correlationbetween the two atoms. It is shown that the amount of quantum discord andentanglement of the two atoms can be improved by applying the bang-bang pulses.
