Abstract

coherence, it is considered a two qubits systems exposed to a common reservoir at very low temperatures. Quantum Information associated to the two qubits system has both a classical contribution and a quantum contribution . It is derived the respective expression for both classical correlations and quantum correlations as a function of time. It is considered the case of remote times (t→∞). In such a situation the genuinely quantum limit where the classical correlations vanish and then Quantum Information is genuinely quantum is found. It is shown that the concept of conservation behind generation (loss) of Quantum Information will be proportional to energy conservation of the system at constant temperature. In case of generation (loss) of Quantum Information the system will absorb (transfer) internal energy from (towards) the environment.
