El 3 de abril tendremos un seminario impartido por Ignacio Solá, de la Universidad Complutense de Madrid
The famous Feynman's lecture "There is plenty of room at the bottom" offered an inspired invitation to explore Nanotechnology. On the verge of a new quantum revolution, we are now expecting a change in the opposite direction, from the small to the macroscopic world, developing quantum operating machines. To this end, several quantum technologies are being developed. One of them is quantum control, which adapts the engineering optimal control theory to find strategies that maximize the desire outcome of quantum processes. We will roughly review some of its template solutions focusing on very generic quantum resources that can be used to control the simplest molecular processes of molecules interacting with light.
Of major importance both conceptually and from a practical point of view is to understand what is the physical source of the control. Is it quantum or classical? And if it is the former, is the quantum world more controllable than its corresponding classical version by virtue of the superposition principle and its wave-like interference properties? Or does the quantum uncertainty put strong limitations in our ability to manipulate matter?
As a very simple but remarkably important example, we will focus on the simplest conceivable system: a two-level system or qubit under coherent excitation, where one can observe Rabi oscillations that lead to full population transfer and full population return. We will illustrate how on more complex multilevel systems one can force or find Rabi-type oscillations underneath their dynamics, unearthing the hidden Rabi oscillations by engineering the initial state of the quantum system or by exploiting some topological features of the Hamiltonian.
