Quantum Correlations in System of Single Jaynes-Cummings Atom and an Isolated Atom

Abstract

Abstract: It mainly studies various correlations in the system of single Jaynes-Cummings（J-C）atom and an isolated atom via the measurement of geometric quantum discord proposed by Dakic et.al. The dynamical evolutions of geometric quantum discord between two atoms are numerically analyzed as well as those of the quantum entanglement and quantum discord.Results show that quantum correlations can be increased by increasing initial entanglement and purity of the prepared W-state of the two atoms. The coupling constant and photon number may also play a significant role in the quantum correlation dynamics.

Key words: quantum optics；Jaynes-Cummings model；quantum entanglement； quantum discord；geometrical quantum discord
