摘要：

We investigate the conditions for the existence of states less exposed to the environment and decoherence-free subspaces (DFS) for two oscillators subjected to reservoirs at any temperature. We show that the main effect of the temperature is to fasten the decoherence process. However, the DFS found for zero temperature remain protected. A solution for diffusive environments is presented.
