摘要：
We present a simple quantum open system to show quantitatively how entanglement decoherence is related to the energy transfer between the system of interest and its environment. Particularly, in the case of the exact entanglement decoherence of two qubits, we find an upper bound for the energy transfer between the two-qubit system and its environments. (c) 2006 Elsevier B.V.
