In order to avoid unwanted effects where the signal of the two qubits is lost (decoherence), it is considered a two qubits system exposed to a common reservoir at very low temperatures. It is derived as an expression for Mutual Quantum Information. Such a quantity has a classical component and also a quantum component. It is found to be a strictly quantum limit where classical correlations vanish. By invoking the First Law of Thermodynamics, it is shown that the concept of conservation behind the generation (loss) of Mutual Quantum Information will be proportional to the 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.
