Quantum algorithms process information encoded into quantum states via an appropriate unitary transformation. Their purpose is to deliver a sought-after target state that represents the solution of a predefined computational problem. From a physical perspective, this process can be interpreted as a quantum state control problem where a given target state is to be prepared through an optimally tailored unitary transformation. In this talk we adopt the one-atom (or micro-) maser as a model to study the transfer of quantum information in state space. We consider a string of atoms that interact sequentially with a cavity mode, to understand the relation between the cavity's convergence towards a given target state and the entanglement content of the injected atomic string.
