  Quantum information processing tasks require exotic quantum states as a
prerequisite. They are usually prepared with many different methods tailored to
the specific resource state. Here we provide a versatile unified state
preparation scheme based on a driven quantum network composed of
randomly-coupled fermionic nodes. The output of such a system is then
superposed with the help of linear mixing where weights and phases are trained
in order to obtain desired output quantum states. We explicitly show that our
method is robust and can be utilized to create almost perfect maximally
entangled, NOON, W, cluster, and discorded states. Furthermore, the treatment
includes energy decay in the system as well as dephasing and depolarization.
Under these noisy conditions we show that the target states are achieved with
high fidelity by tuning controllable parameters and providing sufficient
strength to the driving of the quantum network. Finally, in very noisy systems,
where noise is comparable to the driving strength, we show how to concentrate
entanglement by mixing more states in a larger network.
