  In this work, we study the quantum Fisher information (QFI) per particle of
an open (particles can enter and leave the system) and dissipative (far from
thermodynamical equilibrium) steady state system of two qubits in noisy
channels. We concentrate on two noisy channels these are dephasing and
non-dephasing channels. We will show that under certain conditions QFI per
particle is slightly greater than 1 for both systems. This means that both
systems can be slightly entangled.
