Paper Abstract

In this paper, we have calculated the entanglement degrees of a two-level atom in the one-dimensional photonic crystals heat reservoir, researched the effect of parameter q on the quantum entanglement degrees, and given the quantum entanglement degrees curves with time evolution. We have taken the parameter q=1, 2, 3.5 and 8.5. Our results show when the parameter q=2, keep the time of entanglement degrees near E=1 longest, it is helpful to quantum communication. Furthermore, we have designed the one-dimensional photonic crystals heat reservoir, which meet the parameter q=1, 2, 3.5 and 8.5. These can guide the fabrication of quantum devices based on photonic crystals.
