- Abstract: In this article, we develop a description of topological pumps as slow
classical dynamical variables coupled by a quantum system. We discuss the cases
of quantum Hall pumps, Thouless pumps, and the more recent Floquet pumps based
frequency converters. This last case corresponds to a quantum topological
coupling between classical modes described by action-angle variables on which
we focus. We propose a realization of such a topological coupler based on a
superconducting qutrit suitably driven by three modulated drives. A detailed
experimental protocol allowing to measure the quantized topological power
transfer between the different modes of a superconducting circuit is discussed.

A test current pulse of fixed energy and adjustable length acquires quantum features after interacting with the quantum vacuum of the photon field.
As the length of the pulse grows with respect to the characteristic size of the quantum system, the test pulse undergoes quantum-to-classical transition.
This model differs from previous ones for its simplicity and points towards a new way of creating correlated systems suitable for quantum-based technology.
