Séminaire exceptionnel du LPTMS : Paolo Solinas

Decoherence of adiabatically steered quantum system

Paolo Solinas, Aalto University, Espoo, Finland

In the seminar I will present our results about the effect of Markovian environmental noise on the dynamics of a two-level quantum system which is steered adiabatically by an external driving field. I will discuss the approximations to arrive to a master equation and, in particular, the secular approximation and its consequences on the predicted dynamics. The master equation will be used to describe the superconducting Cooper pair pumping in presence of environmental noise.
I will show how, in the adiabatic limit, the ground state Cooper pair pumping is robust against zero-temperature environment. I will also discuss the possibility to engineer the environmental noise in the above physical set-up and future experiments.
