Correlation quantum beats induced by non-Markovian effect
arXiv:1306.0950 · doi:10.1007/s11128-012-0437-0
Abstract
For two qubits independently coupled to their respective structured reservoirs (Lorentzian spectrum), quantum beats for entanglement and discord are found which are the result of quantum interference between correlation oscillations induced by local non-Markovian environments. We also discuss the preservation of quantum correlations by the effective suppression of the spontaneous emission.
